TC2模型下h_t^0→π_t^+W^-衰变过程的研究

Decay Process of h_t^0→π_t^+W^- in TC2 Model

TC2模型是高能物理研究热点之一,而top-Higgs粒子与top-pion粒子均为TC2模型中重要的特征粒子.在假设top-Higgs的质量大于top-pion和W玻色子质量和的前提下,研究了h_t～0→π_t～+W～-衰变过程,其结果可以用来修正top-Higgs总衰变宽度及其衰变的分支比.

TC2 model is one of the hot spots in high energy physics studies.The top-Higgs and top-pions are both important characteristic particles of the TC2 model.With the premise of assumption which is the mass of top-Higgs is larger than the sum of the top-pion and W boson,decay process of h_t～0→π_t～＋W～- is studied.And the result can be used to correct the whole decay width and the branching ratio of the top-Higgs.
