  We study the discovery potential of the $cg \to tA\to tZH$ process at the
LHC, where $A$ and $H$ are CP-odd and even exotic scalars, respectively. The
context is the general Two Higgs Doublet Model, where $cg \to tA$ is induced by
the flavor changing neutral Higgs coupling $\rho_{tc}$. We find that the
process $cg \to tA\to tZH$ can be discovered for $m_A \sim 400$ 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 $cg \to tA\to tZh$, where $h$ is the observed 125 GeV scalar, but
find it out of reach at the LHC.
