摘要:

在标准模型之外的许多新物理方案中,矢量类夸克的势被预言。本文研究了在大型强子电子对撞机(LHeC)上,在模型无关的框架下,探测到类矢量底夸克($B$)为带电荷$-1/3$的$SU(2)$单线态的可能性.探讨了VLQ- $B$在LHeC上的衰变性质和单次产生。三种类型的签名进行了研究。通过对信号和相应背景进行快速仿真,得到信号的显著性。数值结果表明,通过半轻子通道探测VLQ- $B$比通过全强子或轻子通道探测VLQ- $B$要好。

英文摘要:

Existences of vector-like quarks (VLQs) are predicted in many new physics scenarios beyond the Standard Model (SM). We study the possibility of detecting the vector-like bottom quark (VLQ-$B$) being the $SU(2)$ singlet with electric charge $-1/3$ at the Large Hadron Electron Collider (LHeC) in a model-independent framework. The decay properties and single production of VLQ-$B$ at the LHeC are explored. Three types of signatures are investigated. By carrying out a fast simulation for the signals and the corresponding backgrounds, the signal significances are obtained. Our numerical results show that detecting of VLQ-$B$ via the semileptonic channel is better than via the fully hadronic or leptonic channel.
