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

TL;DR

This paper investigates the detection of gauge-phobic heavy Higgs bosons at high-energy colliders like the LHC and SppC, focusing on the $pp o tar{t}tar{t}$ process and jet substructure techniques.

Contribution

It introduces a method to determine the mass of gauge-phobic heavy Higgs bosons using $p_T$ distributions and demonstrates the potential to observe resonances at future colliders.

Findings

Mass of GPHB can be extracted from $p_T(b_1)$ distributions.

Resonance peaks for $M_H=800$ GeV and 1 TeV can be observed at SppC.

The study provides a viable search strategy for gauge-phobic heavy Higgs bosons.

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.
