( 一 ) TC2 理论典型特征( 二 ) some processes in the model( 三 ) 结论

PROBING TC2: Z’, TOP-PION, TOP-HIGGS

1.TC interaction 主要是破缺 EWS2.ETC 提供费米子质量和一小部分 top 质量3.Topcolor 产生大部分 top 质量和一点 EWSB4. 动力学破缺之后产生 3 个 TC NGBs,3 个 <tt> NGBs, 线性结合之后， TC NGBs 变 成 W 和 Z 的纵分量，其他垂直的 3 个分量

则 成为同位旋 3 重态 top-pion5. 为产生 top 质量， <tt> 凝聚又产生了 cp-even

的 top-higgs

Intersect CILC with LHC

BUT, this is a quite misleading statement －

1. Higgs Boson may be heavy.

2. Higgs may be more than one and charged.

3. Higgs Boson may be composite.

4. Higgs Boson may Not exit at all.

5. Smoking-Gun Signals other than Higgs.

Top mass is much larger than bottom mass

Top propagator depression

Cross section reach 1fb and 100fb for neutral and charged top-pion production

Due to the small backgrounds, it is possible to detect especially for the charged top-pion

Strong dynamics EWSB may predict new particles with anomalous couplings

They may induce observable phenomenology
