Technicolor and other theories of dynamical electroweak symmetry breaking invoke chiral symmetry breaking triggered by strong gauge-dynamics, analogous to that found in QCD, to explain the observed W,...

Improved Spectroscopy of Minimal Walking Technicolor
Improved Spectroscopy Minimal Walking Technicolor
2011/1/6
We present an improved study of spectroscopic observables in the $SU(2)$ Yang-Mills theory with two adjoint fermions. We make an improvement on the precision of previous results which clarify the scal...
Single top production associated with a neutral scalar at LHC in topcolor-assisted technicolor
top quark technicolor LHC
2009/8/14
The topcolor-assisted technicolor (TC2) model predicts a number of neutral scalars like the top-pion (π0t) and the top-Higgs (h0t). These scalars have flavor-changing neutral-current (FCNC) top quark ...
计算了Technicolor理论中的赝标格尔斯通粒子对t→W+b过程的单圈贡献,并讨论了这种贡献对t夸克和赝标格尔斯通粒子质量的依赖性.可以得出:当mt在100—200GeV之间变化时,总的Technicolor单圈贡献从0.6%变到-2.0%.
在一代Technicolor模型下对内含的半轻子B衰变的()阶修正进行了计算. 将理论的预言与最近的实验结果比较,得到了荷电的色单态和色八重态赝标量粒子质量的下限:mp43GeV, MP877GeV.
研究Multiscale Walking Technicolor模型(MWTCM)中赝标戈尔斯通玻色子(PGB)对b→sγ分支比的修正,发现修正太大以致很难解释最近CLEO的实验数据,如果进一步引入Topcolor,在Topcolor assistedMWTCM中,BR(b→sγ)在参数的一定空间内同CLEO的实验数据一致.
