摘　　要：In this study,we explore the detectability of heavy Higgs bosons in the pp→bbH/A→bbtt channel at a100 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 10TeV to ensure detectability.At a collider with an integrated luminosity of 3 ab^(-1),the potential for detecting heavy Higgs bosons varies significantly with their mass and tanβ.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 tanβ smaller than 20 can be detected,whereas those with tanβ larger than 20 are beyond the current discovery or exclusion capabilities.
