Description
We present a study of flavor changing neutral Higgs (FCNH) interactions
in $ p p \to t \bar{t} \to t c h^0 \to t c W W^* + X$, at the Large Hadron
Collider(LHC) with collider energy $\sqrt{s} =$ 13 TeV and 14 TeV.
A general two Higgs doublet model (2HDM) is chosen to study
flavor changing top decays involving the neutral Higgs boson ($t \to c h^0$)
with particular emphasis on the final state of leptons and missing transverse
energy $h^0 \to W W^* \to l \nu l \nu $.
Since the LHC produces top quark pairs abundently, we expect this channel
to provide a clean FCNH signature between the top and the charm quarks at LHC.
We include physics background in the Standard Model with realistic acceptance
cuts to the find discoverable regions in the parameter space.
Furthermore, we investigate the discovery potential of future hadron
colliders with $\sqrt{s} =$ 33 TeV and 100 TeV.
