Probing gauge-phobic heavy Higgs bosons at high energy hadron colliders

We study the probe of the gauge-phobic (or nearly gauge-phobic) heavy Higgs bosons (GPHB) at high energy hadron colliders including the 14 TeV LHC and the 50 TeV Super Proton-Proton Collider (SppC). We take the process pp -> t (t) over bart (t) over bar, and study it at the hadron level including simulating the jet formation and top quark tagging (with jet substructure). We show that, for a GPHB with M-H < 800 GeV, M-H can be determined by adjusting the value of M-H in the theoretical P-T(b(1)) distribution to fit the observed P-T(b(1)) distribution, and the resonance peak can be seen at the SppC for M-H = 800 GeV and 1 TeV.
