The new vector-like quarks are predicted by several new physics beyond the Standard Model at the TeV scale. In this paper, we study single production of vector-like quark T with electric charge in the framework of a simplified model. We investigate the discovery potential of heavy vector-like T-quark decaying into a top quark and a Z boson in trilepton final states, at the future 100 TeV pp colliders including the realistic detector effects. The 95% confidence level (CL) excluded regions and the 5σ discovery reach in the parameter plane between the mass of T-quark and the coupling parameter , are obtained at a 100 TeV pp collider with the integrated luminosity of 30 ab−1. The projected sensitivity in terms of the production cross section times branching fraction is also predicted for 5% systematic uncertainty.

在未来的100辆TeV强子对撞机上,在trilepton通道中单次生成类似矢量的顶级伙伴
在TeV尺度上,除了标准模型之外,新的类似矢量的夸克还可以通过几种新的物理学方法进行预测。本文研究带电荷的类矢量夸克T的单次生产在简化模型的框架中。我们研究了在未来的100 TeV pp对撞机(包括现实的探测器效应)下,重矢量状T夸克在trilepton最终状态中衰减成顶夸克和Z玻色子的发现潜力。95%的置信水平(CL)排除区域和5 σ中的质量之间的参数平面发现到达Ť -quark和耦合参数在100 TeV pp对撞机上获得,积分光度为30 ab -1。以生产横截面时间乘以支化分数的方式预测的灵敏度也可预测为5%的系统不确定性。
