| contents | We investigate the LHC discovery prospects for charged Higgs bosons in the general two Higgs doublet model (G2HDM) that has flavor-changing neutral Higgs (FCNH) couplings. The FCNH $ρ_{tc}$ coupling induces intriguing $H^+$ production processes $c\bar b \to H^+$, $cg \to bH^+$, and $\bar bg \to \bar cH^+$ without CKM suppression. Sizable $ρ_{tc}$ can drive the disappearance of antimatter from the Universe. In this contribution, we promote the resonant $c\bar b \to H^+$ production, followed by the bosonic $H^+ \to W^+ H$ decay. Discovery could be a harbinger of G2HDM with FCNH couplings, and perhaps shed light on the baryon asymmetry of the Universe. |
