ILC T宇称最小Higgs模型中的变味底夸克和反奇夸克产生

摘要:

在具有T宇称的最小Higgs模型(LHT)中,镜夸克引入了特殊的味结构和一些新的味变化(FC)耦合,这些味变化耦合可以极大地提高FC过程的产生率。本文研究了国际直线对撞机(ILC)LHT模型中的一些底部和反奇异产生过程,即,$e^+e^-\to b\bar{s}$和$γγ\to b\bar{s}$。结果表明,这些工艺的生产率是相当大的参数的有利值。因此,通过在迭代学习控制器上对这些过程的检测,可以对LHT模型进行检验或对LHT的相关参数进行约束。

英文摘要:

In the littlest Higgs model with T-parity (LHT) the mirror quarks induce the special flavor structures and some new flavor-changing (FC) couplings which could greatly enhance the production rates of the FC processes. We in this paper study some bottom and anti-strange production processes in the LHT model at the International Linear Collider (ILC), i.e., $e^+e^-\to b\bar{s}$ and $γγ\to b\bar{s}$. The results show that the production rates of these processes are sizeable for the favorable values of the parameters. Therefore, it is quite possible to test the LHT model or make some constrains on the relevant parameters of the LHT through the detection of these processes at the ILC.
