Özet

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) andW boson (W -> q (q) over bar'). 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 < m(B/X) < 3000 GeV) for the relative width Gamma(B/X)/m(B/X) = 0.1 and Gamma(B/X)/m(B/X) = 0.01 of vectorlike B/X quarks have been investigated. From the results of the analysis, the masses of vectorlike quarks B(X) up to 2491 (2364) GeVand 2018 (1873) GeV can be excluded corresponding to these relative width cases at 95% CL depending on the type and branching scenarios at integrated luminosity projection of 3 ab(-1) at the HL-LHC.
