The context is the general two Higgs doublet model, where cg→tA is induced by the flavor changing neutral Higgs coupling ρtc. We find that the process cg→tA→tZH can be discovered for mA?400 GeV, but would likely require high luminosity running of the LHC. Such a discovery would shed light on the mechanism behind the observed baryon asymmetry of the Universe. We also study cg→tA→tZh, where h is the observed 125 GeV scalar, but find it out of reach at the LHC. ? 2020 authors.
