Hadronic flavor violation in pp -> t phi + X and p p -> t t~ -> bjjc phi +X channels at the LHC

We present a study of flavor changing neutral Higgs interaction in $p p \rightarrow t \phi^0 + X $ and $ p p \rightarrow t\bar{t} \rightarrow b j j c \phi^0 + X$ , where $\phi^0$ = $h^0 $ or $H^0$ , at the Large Hadron Collider(LHC). We choose a general two Higgs doublet model (2HDM) to study the $g_{htc}$ couplings with particular emphasis on the $\phi^0 \rightarrow W W \rightarrow l \nu l \nu $ decay channel. With high top production cross section at the LHC,we expect these low background channels to provide a clean signature of flavor changing neutral current among up-type quarks in the Higgs sector and conduct detector simulations to study the visibility and significance of our signal for several values of Higgs masses and the $g_{htc} $ couplings at the LHC. We include standard model (SM) physics background with realistic acceptance cuts at $\sqrt{s}$ = 13 TeV and 14 TeV.
