The $tZH$ and $tZh$ production in 2HDM: Prospects for discovery at the LHC

Abstract

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.
