Measurement of jet fragmentation in 5.02 TeVproton–lead and proton–proton collisions with the

ATLAS detector

The ATLAS Collaboration

A measurement of the fragmentation functions of jets into charged particles in p+Pb colli-sions and pp collisions is presented. The analysis utilizes 28 nb−1 of p+Pb data and 26 pb−1

of pp data, both at √sNN = 5.02 TeV, collected in 2013 and 2015, respectively, with theATLAS detector at the LHC. The measurement is reported in the centre-of-mass frame ofthe nucleon–nucleon system for jets in the rapidity range |y∗| <1.6 and with transverse mo-mentum 45 < pT < 260 GeV. Results are presented both as a function of the charged-particletransverse momentum and as a function of the longitudinal momentum fraction of the particlewith respect to the jet. The pp fragmentation functions are compared with results from MonteCarlo event generators and two theoretical models. The ratios of the p+Pb to pp fragmenta-tion functions are found to be consistent with unity.

1 Introduction

Heavy-ion collisions at the Large Hadron Collider (LHC) are performed in order to produce and studythe quark–gluon plasma (QGP), a phase of strongly interacting matter which emerges at very high energydensities; a recent review can be found in Ref. [1]. Measurements of jets and jet properties in heavy-ioncollisions are sensitive to the properties of the QGP. In order to quantify jet modifications in heavy-ioncollisions, proton–proton (pp) collisions are often used as a reference system. Using this reference, ratesof jet production in Pb+Pb collisions are observed to be reduced compared to that expected from therates in pp collisions, appropriately scaled to account for the nuclear thickness in Pb+Pb collisions [2, 3].Charged-particle fragmentation functions are also observed to be modified in Pb+Pb collisions comparedto pp collisions [4–6]. Both of these effects are interpreted as arising predominantly from the modificationof the parton showering process in the final stages of the collision.

In addition to final-state differences emerging from the presence of the hot and dense matter, jet produc-tion in Pb+Pb collisions may also differ from that in pp collisions due to effects arising from the presenceof the large nucleus. For example, nucleons bound in a nucleus are expected to have a modified struc-ture compared to the free nucleon [7], and partons may lose energy in the nuclear environment beforescattering [8]. Proton–nucleus collisions are used to differentiate between initial- and final-state effectsin Pb+Pb collisions. The inclusive jet production rate in proton–lead (p+Pb) collisions at 5.02 TeV wasmeasured [9–11] at the LHC and found to be only slightly modified after normalization by the nuclearthickness function. Measurements made at the Relativistic Heavy Ion Collider with deuteron–gold col-lisions yield similar results [12] (interestingly, Refs. [9, 12] observe a centrality dependence to inclusivejet production). High transverse momentum (pT) charged hadrons originate from the fragmentation ofjets and provide a complementary observable to that of jet production. The CMS Collaboration observeda small excess in the charged-particle spectrum measured in p+Pb collisions for pT > 20 GeV particlescompared to that expected from pp collisions [13]. Measurements of charged-particle fragmentationfunctions for jets in different pT intervals in p+Pb and pp collisions are crucial for connecting the jetand charged-particle results. Therefore, the measurements reported here are necessary both to establish areference for jet fragmentation measurements in Pb+Pb collisions and to determine any modifications tojet fragmentation in p+Pb collisions due to the presence of a large nucleus.

In recent years many of the features of Pb+Pb collisions which were interpreted as final state effects dueto hot nuclear matter were also observed in p+Pb collisions at the LHC and in d+Au collisions at RHIC.These features include long-range hadron correlations [14–17] and a centrality-dependent reduction inthe quarkonia yields [18–21]. There is considerable debate about whether these features arise from thesame source as in Pb+Pb collisions [22] or from other effects such as initial state gluon saturation [23].Measurements of jets in p+Pb collisions showed no effects that would be attributable to hot nuclearmatter, however additional measurements of jet properties in these collisions could help to constrain thesource of the modifications observed in other observables.

In this paper, the jet momentum structure in pp and p+Pb collisions is studied using the distributions ofcharged particles associated with jets which have a transverse momentum pjet

T in the range 45 to 260 GeV.Jets are reconstructed with the anti-kt algorithm [24] using a radius parameter R = 0.4. Charged particlesare assigned to jets via an angular matching ∆R < 0.4,1 where ∆R is the angular distance between the

The x-axis points from the IP to the centre of the LHC ring, and the y-axis pointsupward. Cylindrical coordinates (r, φ) are used in the transverse plane, φ being the azimuthal angle around the beam pipe.The pseudorapidity is defined in terms of the polar angle θ as η = − ln tan(θ/2).

The fragmentation functions are compared in p+Pb and pp collisions at a centre-of-mass energy of5.02 TeV. In order to quantify any difference between p+Pb and pp collisions, the ratios of the frag-mentation functions are measured:

In Pb+Pb collisions, such measurements are also presented as a function of charged-particle pT [4, 6]to explore the absolute pT scale of the modifications and to reduce jet-related uncertainties. Thus, inaddition to the more commonly used fragmentation functions as a function of z, this Letter also presentsthe analogous distributions and their ratios as a function of charged particle pT:

2 Experimental set-up

The measurements presented here are performed using the ATLAS calorimeter, inner detector, trigger,and data acquisition systems [25]. The calorimeter system consists of a sampling liquid argon (LAr)electromagnetic (EM) calorimeter covering |η| < 3.2, a steel–scintillator sampling hadronic calorimetercovering |η| < 1.7, a LAr hadronic calorimeter covering 1.5 < |η| < 3.2, and two LAr forward calori-meters (FCal) covering 3.2 < |η| < 4.9. The hadronic calorimeter has three sampling layers longitudinalin shower depth. The EM calorimeters are segmented longitudinally in shower depth into three layersplus an additional pre-sampler layer. The EM calorimeter has a granularity that varies with layer andpseudorapidity, but which is generally much finer than that of the hadronic calorimeter. The minimum-bias trigger scintillators (MBTS) [25] detect charged particles over 2.1 < |η| < 3.9 using two segmentedcounters placed at z = ±3.6 m. Each counter provides measurements of both the pulse heights and thearrival times of ionization energy deposits.

A two-level trigger system was used to select the p+Pb and pp collisions analysed here. The first, thehardware-based trigger stage Level-1, is implemented with custom electronics. The second level is thesoftware-based High Level Trigger (HLT). Jet events were selected by the HLT with Level-1 seeds from

jet, minimum-bias, and total-energy triggers. The total-energy trigger required a total transverse energymeasured in the calorimeter of greater than 5 GeV. The HLT jet trigger operated a jet reconstructionalgorithm similar to that applied in the offline analysis and selected events containing jets with transverseenergy thresholds ranging from 20 GeV to 75 GeV in p+Pb collisions and up to 85 GeV in pp collisions.In both the pp and p+Pb collisions, the highest-threshold jet trigger sampled the full delivered luminosity.Minimum-bias p+Pb events were required to have at least one hit in a counter on each side of the MBTSdetector at the Level-1 trigger.

The inner detector measures charged-particle tracks within the pseudorapidity interval |η| < 2.5 usinga combination of silicon pixel detectors, silicon microstrip detectors (SCT), and a straw-tube transitionradiation tracker (TRT), all immersed in a 2 T axial magnetic field [25]. Each of the three detectors iscomposed of a barrel and two symmetric end-cap sections. The pixel detector is composed of three layersof sensors with a nominal pixel size of 50 µm × 400 µm. Following the p+Pb data-taking and prior tothe 5 TeV pp data-taking an additional silicon tracking layer, the “insertable B-layer” (IBL) [26], wasinstalled closer to the interaction point than the other three layers. The SCT barrel section contains fourlayers of modules with 80 µm pitch sensors on both sides, and each end-cap consists of nine layers ofdouble-sided modules with radial strips having a mean pitch of 80 µm. The two sides of each SCT layerin both the barrel and the end-caps have a relative stereo angle of 40 mrad. The TRT contains up to 73(160) layers of staggered straws interleaved with fibres in the barrel (end-cap).

3 Event selection and data sets

The p+Pb data used in this analysis were recorded in 2013. The LHC was configured with a 4 TeV protonbeam and a 1.57 TeV per nucleon Pb beam producing collisions with √sNN = 5.02 TeV and a rapidityshift of the centre-of-mass frame, ∆y = 0.465, relative to the laboratory frame. The data collection wassplit into two periods with opposite beam configurations. The first period consists of approximately 55%of the integrated luminosity with the Pb beam travelling toward positive rapidity and the proton beam tonegative rapidity. The remaining data were taken with the beams of protons and Pb nuclei swapped. Thetotal p+Pb integrated luminosity is 28 nb−1. Approximately 26 pb−1 of

√s = 5.02 TeV pp data from

2015 was used. The instantaneous luminosity conditions provided by the LHC resulted in an averagenumber of p+Pb interactions per bunch crossing of 0.03. During pp data-taking, the average number ofinteractions per bunch crossing varied from 0.6 to 1.3.

The p+Pb events selected are required to have a reconstructed vertex, at least one hit in each MBTSdetector, and a time difference measured between the two MBTS sides of less than 10 ns. The pp eventsused in this analysis are required to have a reconstructed vertex; no requirement on the signal in the MBTSdetector is imposed. In p+Pb collisions the event centrality is determined by the FCal in the Pb-goingdirection as in Ref. [9]. The p+Pb events used here belong to the 0–90% centrality interval.

The performance of the ATLAS detector and offline analysis in measuring fragmentation functions inp+Pb collisions is evaluated using a sample of Monte Carlo (MC) events obtained by overlaying simu-lated hard-scattering pp events generated with Pythia version 6.423 (Pythia6) [27] onto minimum-biasp+Pb events recorded during the same data-taking period. A sample consisting of 2.4×107 pp events isgenerated with Pythia6 using parameter values from the AUET2B tune [28] and the CTEQ6L1 partondistribution function (PDF) set [29], at

√s = 5.02 TeV and with a rapidity shift equivalent to that in the

p+Pb collisions is used in the overlay procedure. About half of the events are simulated with one beamconfiguration and the second half with the other. The detector response is simulated using GEANT4 [30,

4

31], and the simulated hits are combined with those from the data event. An additional sample of 2.6×107

pp hard-scattering events simulated with Pythia version 8.212 (Pythia8) [32] at√

s = 5.02 TeV with theA14 tune [33] and NNPDF23LO PDF set [34] is used to evaluate the performance for measuring frag-mentation functions in the 2015 pp data. Finally, fragmentation functions at generator-level evaluatedfrom 1.5×107 5.02 TeV pp events [35] generated with Herwig++ using the UEEE5 tune [36] and theCTEQ6L1 PDFs [29] are compared to the fragmentation function measured in 5.02 TeV pp data.

4 Jet and track selection

Jets are reconstructed with the same heavy-ion jet reconstruction algorithm used in previous measure-ments in p+Pb collisions [9]. The anti-kt algorithm [24] is first run in four-momentum recombinationmode using as input the signal in ∆η×∆φ = 0.1×0.1 calorimeter towers with the anti-kt radius parameterR set to 0.4 and 0.2 (R = 0.4 jets are used for the main analysis and the R = 0.2 jets are used to improvethe jet position resolution as discussed below). The energies in the towers are obtained by summing theenergies of calorimeter cells at the electromagnetic energy scale within the tower boundaries. Then, aniterative procedure is used to estimate the layer- and η-dependent underlying event (UE) transverse en-ergy density, while excluding the regions populated by jets. The UE transverse energy is subtracted fromeach calorimeter cell and the four-momentum of the jet is updated accordingly. Then, a jet η- and pT-dependent correction factor derived from the simulation samples is applied to correct the jet momentumfor the calorimeter response. Additionally, the jet energies were corrected by a multiplicative factor de-rived in in situ studies of the transverse momentum balance of jets recoiling against photons, Z bosons,and jets in other regions of the calorimeter [37, 38]. This in situ calibration, which typically differed fromunity by a few percent, accounts for differences between the simulated detector response and data.

Jets are required to have jet centre-of-mass rapidity, |y∗jet| < 1.6,3 which is the largest symmetric overlapbetween the two collision systems for which there is full charged-particle tracking coverage within a jetcone of size R = 0.4. To prevent neighbouring jets from distorting the measurement of the fragmentationfunctions, jets are rejected if there is another jet with higher pT within a distance δR = 1.0, where δR is thedistance between the two jet axes. To reduce the effects of the broadening of the jet position measurementdue to the UE, for R = 0.4 jets, the jet direction is taken from that of the closest matching R = 0.2 jetwithin δR = 0.3 when such a matching jet is found (this procedure has been previously used in Ref. [5]).All jets included in the analysis are required to have pT sufficiently large for the jet trigger efficiencyto be higher than 99%. Reconstructed jets which consist only of isolated high-pT electrons [39] fromelectroweak bosons are excluded from this analysis.

The MC samples are used to evaluate the jet reconstruction performance and to correct the measureddistributions for detector effects. The p+Pb jet reconstruction performance is described in Ref. [9]; the jetreconstruction performance in pp collisions is found to be similar to that in p+Pb collisions. In the MCsamples, the kinematics of the particle-level jets are reconstructed from primary particles4 with the anti-kt

algorithm with radius parameter R = 0.4. In these studies, particle-level jets are matched to reconstructedjets with a ∆R < 0.2.

3 The jet centre-of-mass rapidity y∗jet is defined as y∗jet ≡ yjet − ∆y where yjet is the jet rapidity in the ATLAS rest frame and ∆y

is the rapidity shift of the centre-of-mass frame.4 Primary particles are defined as particles with a mean lifetime τ > 0.3 × 10−10 s either directly produced in pp interactions or

from subsequent decays of particles with a shorter lifetime. All other particles are considered to be secondary.

5

Tracks used in the analysis of p+Pb collisions are required to have at least one hit in the pixel detectorand at least six hits in the SCT. Tracks used in the analysis of pp collisions are required to have at least9 or 11 total silicon hits for |η| < 1.65 or |η| > 1.65, respectively, including both the pixel layers and theSCT. This includes a hit in the first (first or second) pixel layer if expected from the track trajectory for thep+Pb (pp) data. All tracks used in this analysis are required to have pT > 1 GeV. In order to suppress thecontribution of secondary particles, the distance of closest approach of the track to the primary vertex isrequired to be less than 1.5 mm along the beam axis and less than a value which varies from approximately0.6 mm at pT = 1 GeV to approximately 0.2 mm at pT = 20 GeV in the transverse plane.

Figure 1: Tracking efficiency as a function the primary particle momentum at generation level, ptruthT , in pp collisions

(left) and in p+Pb collisions for one of the two beam configurations (right). The different sets of points show theprimary particle pseudorapidity, ηtruth, intervals in which the track reconstruction efficiency has been performed.The different ηtruth intervals in pp and p+Pb plots reflect the different regions of the tracking system used in the twocases due to the boosted p+Pb system. The solid curves show parameterizations of efficiencies.

The efficiency for reconstructing charged particles within jets in p+Pb and pp collisions is evaluated usingPythia6 and Pythia8 MC samples, respectively, and is computed by matching the reconstructed tracksto generator-level primary particles. The association is done based on contributions of generator-levelparticles to the hits in the detector layers. A reconstructed track is matched to a generator-level particle ifit contains hits produced primarily by this particle [31]. The efficiencies are determined separately for thetwo p+Pb running configurations because the η regions of the detector used for the track measurement aredifferent for the two beam configurations. The charged-particle reconstruction efficiencies as a functionof the primary particle’s transverse momentum, ptruth

T , in coarse ηtruth intervals, are shown in Figure 1 inpp and p+Pb collisions. The ptruth

T dependence of the efficiencies is parameterized using a fifth-orderpolynomial in log(ptruth

T ) which describes the efficiency behaviour in the range of particle ptruthT from 1.0

to 150 GeV. The tracking efficiency is observed to be constant above 150 GeV and a constant efficiencyvalue is used for particles with ptruth

T > 150 GeV due to the limited size of the MC samples in thatphase space region. To account for finer scale variations of the tracking efficiency with pseudorapidity,the parameterizations are multiplied by an η-dependent scale factor evaluated in ηtruth intervals of 0.1units in coarse ptruth

T intervals. The dependence of the charged-particle efficiency on pjetT is found to be

negligible for the pjetT selections used here. The measured D(z) and D(pT) distributions are corrected for

the contribution of reconstructed “fake” tracks which cannot be matched to a generated primary particlein the MC samples produced without minimum bias interactions overlaid and the residual contribution oftracks matched to secondary particles. The fraction of secondary and fake tracks is found to be below 2%of the tracks that pass the selection in any track and jet kinematic region. The contribution from thesetracks to the fragmentation functions is subtracted from the measured fragmentation functions in both the

6

pp and p+Pb collisions.

5 Analysis procedure

Reconstructed charged particle tracks are associated with a reconstructed jet if they fall within ∆R =

0.4 of the jet axis. For each of these particles the momentum fraction, z, is calculated. The measuredfragmentation functions are constructed as:

D(z)meas ≡1

Njet

1ε(η, pT)

∆Nch(z)∆z

(5)

andD(pT)meas ≡

1Njet

1ε(η, pT)

∆Nch(pT)∆pT

, (6)

where ε(η, pT) is the track reconstruction efficiency, and Njet is the total number of jets in a given pjetT

bin. The quantities ∆Nch(z) and ∆Nch(pT) are the numbers of associated tracks within the given z or pTrange, respectively. The efficiency correction is applied on a track-by-track basis, assuming pT = ptruth

T .While that assumption is not strictly valid, the efficiency varies sufficiently slowly with ptruth

T that the errorintroduced by this assumption is negligible.

In p+Pb collisions the UE contribution to the fragmentation functions from charged particles not asso-ciated with the jet constitutes a background that needs to be subtracted. It originates in soft interactionsthat accompany the hard process in the same p+Pb collision and depends on charged-particle pT and η.This background is determined event by event for each measured jet by using a grid of ∆R = 0.4 conesthat span the full coverage of the inner detector. The cones have a fixed distance between their centreschosen such that the coverage of the inner detector is maximized while the cones do not overlap eachother. Any such cone containing a charged particle with pT > 3.5 GeV is assumed to be associated witha real jet and is excluded from the UE contribution. The 3.5 GeV threshold is derived from studies ofUE contribution in MC samples. The estimated contribution from UE particles in each cone is correctedto account for differences in the average UE particle yield at a given pT between the η position of thecone and the η position of the jet. The correction is based on a parameterization of the pT and η depend-ence of charged-particle yields in minimum-bias collisions. The resulting UE contribution is evaluatedfor charged particles in the transverse momentum interval of 1 < pT < 3.5 GeV and averaged over allcones. The UE contribution is further corrected for the correlation between the actual UE yield withinthe jet cone and the jet energy resolution discussed in Ref. [5]. This effect is corrected by a multiplicativecorrection factor, dependent on the track pT (or z) and the jet pT. The correction is estimated in MCsamples as the ratio of the UE contribution calculated from tracks within the area of a jet that do not havean associated generator-level particle to the UE contribution estimated by the cone method. Corrected UEcontributions are then subtracted from measured distributions. The maximum size of the UE contributionis 20% for the lowest track pT (or z). The UE from the cone method is compared to an alternative UEestimation and the difference is found to be negligible. The subtracted UE contribution has no azimuthalvariation in p+Pb collisions and no UE subtraction is performed for the pp measurement due to negligibleUE contribution (less than 2% over the entire kinematic range measured).

The measured D(z) and D(pT) distributions are corrected for detector effects by means of a two-dimensionalBayesian unfolding procedure [40] using the RooUnfold package [41]. The unfolding procedure removes

7

the effect of bin migration due to the jet energy and the track momentum resolutions. Using the MCsamples, four-dimensional response matrices are created using the particle-level and reconstructed pjet

T ,and generator-level and reconstructed track pT (z). Separate unfolding matrices are constructed for thep+Pb and pp data. An independent bin-by-bin unfolding procedure is used to correct the measured pjet

Tspectra, which is used to normalize the unfolded fragmentation functions by the number of jets. Theresponse matrices are reweighted such that the shapes of the measured fragmentation functions and jetspectra in the simulation match those in the data. The number of iterations in the Bayesian unfoldingis selected to be the minimum number for which the relative change in the fragmentation function atz = 0.1 is smaller than 0.2% per additional iteration in all pjet

T bins. This condition ensures the stabilityof the unfolding and minimizes statistical fluctuations due to the unfolding in the high z and pT regions.The resulting number of iterations is driven by the low pjet

T intervals, which require the most iterations toconverge. The systematic uncertainty due to the unfolding is typically much larger than the impact of thestability requirement, especially for the lowest pjet

T values used in this analysis (discussed in Section 6).Following this criterion, 14 iterations are used for both the p+Pb and pp data sets. The analysis procedureis tested by dividing the MC event sample in half and using one half to generate response matrices withwhich the other half is unfolded. Good recovery of the generator-level distributions is observed for theunfolded events and the deviations from perfect closure are incorporated into the systematic uncertain-ties.

6 Systematic uncertainties

The systematic uncertainties in the measurement of the fragmentation functions and their ratios are de-scribed in this section. The following sources of systematic uncertainty in the measurement of the frag-mentation functions and their ratios are considered: the jet energy scale (JES), the jet energy resolution(JER), the dependence of the unfolded results on the choice of the starting MC distributions, the residualnon-closure of the unfolding and the tracking-related uncertainties. For each variation reflecting a sys-tematic uncertainty the fragmentation functions are re-evaluated and the difference between the variedand nominal fragmentation functions is used as an estimate of the uncertainty. The systematic uncertain-ties in the D(z) and D(pT) measurements in both collision systems are summarized in Figures 2 and 3,respectively, for two different jet pT bins. The systematic uncertainties from each source are taken asuncorrelated and combined in quadrature to obtain the total systematic uncertainty.

The JES uncertainty is determined from in situ studies of the calorimeter response [37, 42, 43], and studiesof the relative energy-scale difference between the jet reconstruction procedure in heavy-ion collisions andthe procedure used in pp collisions [44]. The impact of the JES uncertainty on the measured distributionsis evaluated by constructing new response matrices where all reconstructed jet transverse momenta areshifted by ±1 standard deviation (±1σ) of the JES uncertainty. The data are then unfolded with thesematrices. Each component that contributes to the JES uncertainty is varied separately. In total, 45 and51 independent systematic components constitute the full JES uncertainty in the analysis of p+Pb andpp collisions, respectively. These components are uncorrelated among each other within the data set andfully correlated across pT and η. The JES uncertainty increases with increasing z and particle pT at fixedpjet

T and decreases with increasing pjetT .

The uncertainty in the fragmentation functions due to the JER is estimated by repeating the unfoldingprocedure with modified response matrices, where the resolution of the reconstructed jet pjet

T is broadenedby Gaussian smearing. The smearing factor is evaluated using an in situ technique involving studies of

dijet energy balance [45, 46]. The systematic uncertainty due to the JER increases with increasing z andparticle pT at fixed pjet

T and decreases with increasing pjetT .

The unfolding uncertainty is estimated by generating the response matrices from the MC distributionswithout reweighting to match the shapes of the reconstructed data in pjet

T and D(z) or D(pT). Conser-vatively, an additional uncertainty to account for possible residual limitations in the analysis procedurewas assigned by evaluating the non-closure of the unfolded distributions in simulations, as described inSection 5. The magnitude of both of these uncertainties is typically below 5% except for the highest zand track pT bins.

The uncertainties related to the track reconstruction and selection originate from several sources. Uncer-tainties related to the rate of secondary and fake tracks, the material description in the simulation, and thetrack’s transverse momentum were obtained from studies in data and simulation described in Ref. [47].The systematic uncertainty in the secondary-track and fake-track rate is 30% in pp collisions and 50%in p+Pb. The contamination by secondary and fake tracks is at most 2%, the resulting uncertainty in thefragmentation functions is at most 1%. The sensitivity of the tracking efficiency to the description of theinactive material in the MC samples is evaluated by varying the material description. This uncertainty isbetween 0.5 and 2% (depending on track η) in the track pT range used in the analysis. Uncertainty in thetracking efficiency due to the high local track density in the cores of jets is 0.4% [48] for all pjet

in this analysis. The uncertainty due to the track selection criteria is evaluated by repeating the analysiswith an additional requirement on the significance of the distance of closest approach of the track to theprimary vertex. This uncertainty affects both the track reconstruction efficiency and the rate of secondaryand fake tracks. The resulting uncertainty typically varies from 1% at low track pT and low z to 5% at hightrack pT and high z. The systematic uncertainties in the fragmentation functions due to the parameteriza-tion of the efficiency corrections is less than 1%. An additional uncertainty takes into account a possibleresidual misalignment of the tracking detectors in pp data-taking. The alignment in this data was checkedin situ with Z → µ+µ− events, and thus a track-pT dependent uncertainty arises from the finite size of thissample. The resulting uncertainties in the fragmentation functions are typically smaller than 1% exceptat large z where they are as large as 4%. Finally, the track-to-particle matching requirements are varied.This variation affects the track reconstruction efficiency, the track momentum resolution, and the rate ofsecondary and fake tracks. The resulting uncertainties in the fragmentation functions are smaller than 1%.After deriving new response matrices and efficiency corrections, the resulting systematic uncertainty inthe fragmentation functions is found to be less than 0.5%. The tracking uncertainties shown in Figures 2and 3 include all the above explained track-related systematic uncertainties added in quadrature.

The correlations between the various systematic components in the two collision systems are consideredwhen taking the ratios of p+Pb to pp fragmentation functions. For the JES uncertainty, each sourceof uncertainty is classified as either correlated or uncorrelated between the two systems depending on

its origin. The JER, unfolding and MC non-closure uncertainties are taken to be uncorrelated. For thetracking-related uncertainties the variation in the selection requirements, tracking in dense environments,secondary-track and fake-track rates, and parameterization of the efficiency corrections are taken as un-correlated. The first three of these are conservatively considered as uncorrelated because the trackingsystem was augmented with the IBL and the tracking algorithm changed between the p+Pb and pp data-taking periods. The uncertainties due to the track-to-particle matching and the inactive material in theMC samples are taken as correlated between p+Pb and pp collisions. For the correlated uncertaintiesthe ratios are re-evaluated applying the variation to both collision systems; the resulting variations ofthe ratios from their central values is used as the correlated systematic uncertainty. The total systematicuncertainties in the RD(z) and RD(pT) distributions are shown in Figures 4 and 5, respectively, for two pjet

Tintervals.

7 Results

The D(z) and D(pT) distributions in both collision systems are shown in Figures 6 and 7, respectively.Figure 8 compares the D(z) distribution in pp collisions at 5.02 TeV to the predictions from three eventgenerators (Pythia6, Pythia8, and Herwig++) using the parameter-value tunes and PDF sets describedin Section 3 for the six pjet

T intervals. The Pythia8 generator provides the best description of the data,generally agreeing within about 5 to 10% over the kinematic range used here. Pythia6 agrees withinapproximately 25% when compared to the data and Herwig++ agrees within approximately 20% exceptfor the highest z region, where there are some larger deviations. Similar agreement with Pythia6 andHerwig++ generators with different tunes than used in this analysis was reported by ATLAS in the meas-urement of fragmentation functions in 7 TeV pp collisions [49]. The tunes of Pythia6 and Pythia8 usedhere include the results from that measurement.

Figure 9 shows the pp fragmentation functions compared to two theoretical calculations. These predic-tions use a slightly different definition of z compared to the definition used in this measurement. Thiscan introduce a difference between the fragmentation functions of approximately 1%. The calculation inRefs. [50, 51] provides fragmentation functions with next-to-leading-order (NLO) accuracy as well as aresummation of logarithms in the jet cone size. The calculation in Ref. [52] is at NLO and uses the ap-

proximation that the jet cone is narrow. For the parton-to-charged-hadron fragmentation functions, bothcalculations use DSS07 fragmentation functions [53]. The uncertainties in the theoretical calculation arenot estimated, including the uncertainty in DSS07, which is common to both calculations. The calcula-tions are systematically higher than the data and generally agree within 20–30%. Larger deviations areobserved at the low and high z regions. The DSS07 fragmentation functions have a minimum z of 0.05and the calculations use extrapolated fragmentation functions in the region below z = 0.05.

Figures 10 and 11 show the ratios of fragmentation functions in p+Pb collisions to those in pp collisions,as a function of z and pT respectively for pjet

T from 45 to 260 GeV. Over the kinematic range selectedhere, the RD(z) and RD(pT) distributions show deviations from unity of up to approximately 5% (up to 10%for 60–80 GeV jet selections) for z < 0.1 and pT < 10 GeV. The deviations are larger than the reportedsystematic uncertainties by at most a couple of percent and always less than 1.5σ of the systematicuncertainties. At higher z and pT values the ratios are consistent with unity. At the highest z points for the160–210 GeV and 210–260 GeV jet selections, deviations from unity of approximately 0.9σ and 1.3σ ofcombined statistical and systematic uncertainties, respectively, are observed. This is not observed in theD(pT) distributions. In most pjet

T bins there is a slight decrease of the central values of RD(z) and RD(pT)with increasing z and pT; however the size of the effect is smaller than the systematic uncertainties.

8 Summary

This paper presents the first measurement of the jet charged-particle fragmentation functions in a p+Acollisions system. The jet charged-particle fragmentation functions are reported for |y∗jet| < 1.6 and pjet

Tfrom 45 to 260 GeV in √sNN = 5.02 TeV p+Pb and pp collisions with the ATLAS detector at the LHC.The measurement utilizes 28 nb−1 of p+Pb data and 26 pb−1 of pp data. The pp fragmentation func-tions are compared to predictions from the Pythia6, Pythia8 and Herwig++ generators. The generatorsshow deviations from the pp data of up to approximately 25%, depending on z and the choice of gen-erator. Pythia8 with the A14 tune and NNPDF23LO PDF set matches the data most closely. The ppD(z) distributions are also compared to two theoretical calculations based on next-to-leading-order QCDand DSS07 fragmentation functions. The calculations are systematically higher than the data and agreegenerally within 20–30%, with larger deviations at small and large values of z. These measurements helpconstrain jet fragmentation in pp collisions. The ratios of fragmentation functions in p+Pb collisions tothose in pp collisions show no evidence for modification of jet fragmentation in p+Pb collisions. Thismeasurement provides new constraints on the modifications to jets in p+Pb collisions at the LHC andis directly relevant to the current investigations into the properties of small collision systems. Finally,these measurements of jet fragmentation functions for different intervals of jet transverse momentumprovide necessary baseline measurements for quantifying the effects of the quark-gluon plasma in Pb+Pbcollisions.
