Single production of vector-like T quark decaying into Wb at the CLIC

Based on a model-independent framework including SU(2) singlet vector-like top partner (VLQ-T), we investigate the prospect of discovering the single production of VLQ-T decaying into Wb in e+e− collisions at 3 TeV Compact Linear Collider (CLIC). By carrying out a full simulation for the signal and the relevant SM backgrounds, we find that for the high integrated luminosity of 3 (5) ab−1, the singlet VLQ-T could be excluded in the correlated region of the coupling parameter g⁎∈[0.17,0.5]([0.15,0.4]) and mass mT∈ [1500 GeV, 2600 GeV] at 2σ level, and the discovered correlation region is g⁎∈[0.27,0.5]([0.24,0.44]) and mT∈ [1500 GeV, 2400 GeV]. The future 3 TeV CLIC is a promising hunting ground for such new particles with electroweak strength interactions.
