We investigate the prospects for discovering a top quark decaying into one light Higgs boson (h⁰) along with a charm quark (c) in top-quark pair production at the CERN LHC and future hadron colliders. A general two Higgs doublet model is adopted to study the signature of flavor changing neutral Higgs interactions with t → ch⁰, followed by h⁰ → WW* → ℓ⁺ℓ^– + E_T, where h0 is the CP-even Higgs boson and E_T stands for missing transverse energy from neutrinos. We study the discovery potential for this flavor changing neutral Higgs signal and physics background from dominant processes with realistic acceptance cuts as well as tagging and mistagging efficiencies. Furthermore, promising results are found for the LHC running at 13 and 14 TeV center-of-mass energy as well as future pp colliders at 27 and 100 TeV.
