LRTH模型中WbT在直线对撞机上的联合产生

WbT Associated Production at Linear Colliders in the Left-Right Twin Higgs Model

在左右双希格斯(LRTH)模型中研究了单顶夸克伴子T与Wb在直线对撞机上的联合产生。计算了过程e^-e^+→W^-bT(W^+bT)和γγ→W^-bT(W^+bT)在质心能量S^(1/2)=2.0 TeV时的产生截面,发现这两个过程的产生截面分别可以达到O'(10~3)fb和O'(10)fb。另外还展示了产生过程中末态粒子典型的运动学分布。

In the framework of the left-right twin Higgs(LRTH)model, this paper analyzes the single top partner Tproduction in association with Wb at linear colliders, and calculates the production cross-sections of the processes e-e+→W-bT(W+bT)and γγ→W-bT(W+bT)at S1/2=2.0 TeV. It finds that the production cross-sections of these two processes can reach O’(103)fb and O’(10)fb,respectively. Besides, some typical differential distributions of the final state particles are displayed.
