Abstract

We consider a general two Higgs doublet model which can simultaneously solve discrepancies in neutral $B$ meson decay ($b\ensuremath{\rightarrow}s\ensuremath{\ell}\overline{\ensuremath{\ell}}$ distribution) and charged $B$ meson decay ($b\ensuremath{\rightarrow}c\ensuremath{\tau}\overline{\ensuremath{\nu}}$) with a charged Higgs. The model contains two additional neutral scalars at the same mass scale and predicts distinctive signals at the LHC. Based on the recent same-sign top search by the ATLAS collaboration, we found the constraint on the scalar mass spectrum. To probe the remaining mass window, we propose a novel $cg\ensuremath{\rightarrow}t\ensuremath{\tau}\overline{\ensuremath{\tau}}$ process at the LHC.
