Searching for flavor changing neutral Higgs interaction in associated single top production at Hadron Colliders.

We investigate the prospect of discovering flavor changing neutral currents in the top associated Higgs production ($\phi^0 = h^0,H^0,A^0$) at the LHC and future hadron colliders. With top decaying to a bottom quark and two light quarks, and Higgs decay to $ZZ, W^+ W^-$ and $\gamma \gamma$, with the following final states, $b j j \ell^+ \ell^- \ell^+ \ell^-$, $b j j \ell^+ \ell^- \nu_{\ell} \bar{\nu}_{\ell}$ and $b j j \gamma \gamma$. We adopt a general two Higgs doublet model, keeping the CP symmetry. We are using Boosted Decision Trees, for classification and to study discovery potential at current center of mass energies of 13 TeV and 14 TeV. We also present results for future HE-LHC and upcoming hadron colliders at $\sqrt{s} =$ 27 TeV and 100 TeV.
