论文摘要
除标准模型（SM）以外的许多新物理场景中预测了类似向量的夸克（VLQ）的存在。我们研究了在一个独立于模型的框架中检测到具有电荷$ -1/3 $的$ su（2）$ singlet的可能性。探索了LHEC的VLQ- $ B $的衰减属性和单一生产。研究了三种类型的签名。通过对信号和相应背景进行快速模拟，可以获得信号意义。我们的数值结果表明，通过半雌科通道检测VLQ-$ b $比通过完全的辐射或松弛通道更好。
Existences of vector-like quarks (VLQs) are predicted in many new physics scenarios beyond the Standard Model (SM). We study the possibility of detecting the vector-like bottom quark (VLQ-$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.
