Abstract

We investigate the discovery potential of the 3 TeV Compact Linear Collider (CLIC) for a singlet vector-like bottom partner B decaying via B → tW. Focusing on the fully hadronic final state BB → tW tW, we reconstruct boosted top and W candidates using large-R Valencia jets, supplemented by a merging strategy for partially resolved decays. A systematic scan of the jet-radius parameter identifies R=0.8 as the optimal choice, balancing boosted-jet containment with jet multiplicity. Using a cut-based analysis optimized for the (2t+2W) topology and an integrated luminosity of 5~\rm ab^-1, CLIC can achieve sensitivity to m_B \lesssim 1.5~\rm TeV. These results highlight CLIC's excellent capability to probe heavy vector-like quarks in high jet multiplicity environments, extending well beyond the reach of current hadron collider searches.
