| contents | Vector-like quarks (VLQs) are introduced in many new physics senarios beyond the Standard Model (SM) to address some problems faced by SM. In this paper, we explore the pair production of TeV-scale vector-like B quark (VLQ-$B$) at the future 3 TeV Compact Linear Collider (CLIC) in simplified effective lagrangian framework. We consider the decay modes of $B\rightarrow bZ$ and $B\rightarrow bh$ followed by hadronic decay of $Z$ and $h$ bosons. The large mass of VLQ-$B$ will induce highly boosted bosons $Z$ or $h$ which are more likely to form as fat-jets. By performing a rapid detector simulation of the signal and background events and clustering the jets with a large radius R, signal-background analyses are carried out. And the exclusion limit at the 95\% confidence level and the 5$σ$ discovery prospects are obtained with an integrated luminosity of 5$\text{ab}^{-1}$. |
