Probing a Vector-like Top Quark \(T \to H^+b\) and \(H^+ \to t \bar b\) at HL-LHC
摘要
In this study, we explore the single production and decay of a vector-like top partner (T) with charge \(2/3\) in the Two Higgs Doublet Model Type II (2HDM-II) extended by a vector-like quark (VLQ) doublet (TB). Focusing on the process , we analyze the final state featuring a lepton, multiple b-jets, and missing transverse energy. This channel demonstrates significant potential for discovering the T quark and the charged Higgs boson ( \(H^+\) ) at the HL-LHC.
