Exploration of heavy Higgs bosons at a 100 TeV hadron collider withinthe semi-constrained next-to-minimal supersymmetric standard model*

In this study, we explore the detectability of heavy Higgs bosons in the channel at a 100 TeV hadron collider within the semi-constrained next-to-minimal supersymmetric standard model. We calculate their production cross sections and decay branching ratios and compare them with simulation results from literature. We focus on the heavy doublet-dominated CP-even Higgs H and CP-odd Higgs A, with mass limits set below 10 TeV to ensure detectability. At a collider with an integrated luminosity of 3 ab , the potential for detecting heavy Higgs bosons varies significantly with their mass and . Heavy Higgs bosons with masses below 2 TeV are within the testable range, while those heavier than 7 TeV are below the exclusion and discovery thresholds, rendering them undetectable. For masses between 2 and 7 TeV, heavy Higgs bosons with smaller than 20 can be detected, whereas those with larger than 20 are beyond the current discovery or exclusion capabilities.
