1 PROBING TC2: Z’, TOP-PION, TOP-HIGGS
柳国丽 (郑州大学) ＠2010年呼伦贝尔会议研讨会 (一) TC2理论典型特征 (二) some processes in the model (三) 结论

2 1.TC interaction 主要是破缺EWS
模型回顾 1.TC interaction 主要是破缺EWS 2.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EWSB 4.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-pion 5.为产生top质量，<tt>凝聚又产生了cp-even的top-higgs

15 Small summary Cross section reach 1 fb May be detected by future ILC
Serve as a probe to TC2

16 Ep collider suggestions
THERA Intersect CILC with LHC Linac-e to LHC and VLHC \gamma :Compton backscattering

17 It is often said that LHC is just to find a light fundamental Higgs Boson
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.

23 Charged Production is larger than neutral
Top mass is much larger than bottom mass Top propagator depression

24 Small summary(2) 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

25 conclusion Strong dynamics EWSB may predict new particles with anomalous couplings They may induce observable phenomenology
