| 英文摘要 | We study the excesses of muon g - 2 and R(D-(*())) in the framework of a two-Higgs-doublet model with top quark flavor-changing neutral-current (FCNC) couplings. Considering the relevant theoretical and experimental constraints, we find that the muon g - 2 and R(D-(*())) excesses can be simultaneously explained in a parameter space allowed by the constraints. In such a parameter space the pseudoscalar (A) has a mass between 20 GeV and 150 GeV so that it can be produced from the top quark FCNC decay t -> Ac. Focusing on its dominant decay A -> tau(tau) over bar, we perform a detailed simulation on pp -> t (t) over bar -> WbAc -> jjbc tau(tau) over bar and find that the 2 sigma upper limits from a data set of 30 (100) fb(-1) at the 13 TeV LHC can mostly (entirely) exclude such a parameter space.
