New vector-like quarks are predicted in many new physics scenarios beyond the Standard Model (SM). Based on a model-independent framework, we investigate the prospect of discovering the SU(2) singlet vector-like bottom quark (VLQ-B) in collisions at 3 TeV Compact Linear Collider. We study the single VLQ-B production process
with two types of decay channel:
, and
. By carrying out a full simulation for the signals and the relevant SM backgrounds, the
exclusion limit and
discovery prospects are, respectively, obtained on the B quark mass and the coupling strength
with the integrated luminosity of 5
. Our numerical results show that the possible signals of the singlet VLQ-B might be detected at the future high-energy
linear colliders.
