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→tt¯tt¯, 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 MH<800 GeVMH<800 GeV, MHMH can be determined by adjusting the value of MHMH in the theoretical pT(b1)pT(b1) distribution to fit the observed pT(b1)pT(b1) distribution, and the resonance peak can be seen at the SppC for MH=800 GeVMH=800 GeV and 1 TeV.
