Induced by the top-flavor changing neutral Higgs coupling ρtc, the process may emerge if mH+>mA+mW+, where H+ and A are charged and CP-odd Higgs bosons in the general two Higgs doublet model (g2HDM). We show that the cg→bH+→bAW+ process can be discovered at LHC run 3, while the full run 2 data at hand can constrain the parameter space significantly by searching for the same-sign dilepton final state. The process has unique implications on the hint of gg→A→tt¯ excess at mA?400 GeV reported by CMS. When combined with other existing constraints, the cg→bH+→bAW+ process can essentially rule out the g2HDM explanation of such an excess. ? 2021 authors.
