| 摘 要： | We study the prospects of probing the anomalous tHq(q=u,c)couplings via SS2L or 3L signatures at the High Luminosity(HL-LHC)run of the 14 Te V CERN collider.We focus on signals of the tH associated production followed by the decay modes t→b?^+ν_?and H→W W~*,and ■ production followed by the decay modes t→b?^+ν_?and■where?=e,μ.Based on two types of H→W W~*decay topologies,one assuming the semileptonic decay mode H→W W~*→?^+νjj and the other the fully leptonic decay mode■,we perform a full simulation for signals and backgrounds.It is shown that,at the future HL-LHC,the branching ratio Br(t→uh)(Br(t→ch))can be probed to 1.17(1.56)×10-3for the same-sign di-lepton channel,and to7.1×10-4(1.39×10-3)for the 3L channel at 3σsensitivity.
