Conclusive probe of the charged Higgs solution of P′₅ and R$_{D^{( * )}}$ discrepancies

We consider a general two Higgs doublet model which can simultaneously solve discrepancies in neutral B meson decay (b→sℓ¯ℓ distribution) and charged B meson decay (b→cτ¯ν) 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→tτ¯τ process at the LHC.
