We investigate the single production of vectorlike quarks at the High Luminosity LHC (HL-LHC). With the assumed (enhanced) couplings to third generation quarks of the standard model, vectorlike quarks B/X are produced in association with a bottom (b) or top (t) quark, which correspond to Bbq and Btq/Xtq production modes, including an additional soft forward jet from the spectator quark (q). This study focuses on high-mass vectorlike quarks B/X decaying into a top quark and a W boson, resulting in the final state jets emerging from hadronically decaying top quark (t→Wb) and W boson (W→qq¯′). The events with W boson and t quark have been analyzed using tagging techniques for large-radius jets. The scan ranges of the mass (1000
