Heavy Higgs bosons at a 100 TeV hadron collider

Abstract

In this work, we consider two heavy Higgs bosons (H and A) of about 2.4 ∼ 4.8 TeV in the semi-constrained NMSSM (scNMSSM) in our previous work. We study them in the pp → b bH/A → b bt t channel at a 100 TeV hardon collider. We calculate their cross section of production and branching ratios of decay, and compare the signal with the simulation result in a reference. We finally find that it is hard to detect the heavy Higgs bosons in this channel at the 100 TeV collider with an integrated luminosity of 3 ab −1 , because their branching ratio to SM particles including t t are seriously suppressed by the decay to SUSY particles. We will add discussions about detecting in other channels later.

“…The parameter space scan are consistent with our previous work [66], using the NMSSMTools-6.0.2 package [67][68][69][70] to conduct the scans and calculate relevant properties. Both theoretical and experimental constraints are considered: theoretical constraints include vacuum stability and absence of Landau poles [67,68]; experimental constraints include flavor constraints [71][72][73][74], a global fit of LHC Higgs data [75][76][77][78][79][80][81], DM relic density [82,83], direct and indirect DM searches [84][85][86][87][88][89].…”
