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

Abstract

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 $pp\to t\bar{t}t\bar{t}$, 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.
