Exploring Heavy Higgs Bosons at a 100 TeV Hadron Collider within the Semi-Constrained NMSSM
Chinese Physics C(2021)
摘要
In this study, we explore the detectability of heavy Higgs bosons in the pp
→ bb̅H/A → bb̅tt̅ channel at a 100 TeV hadron collider
within the semi-constrained Next-to-Minimal Supersymmetric Standard Model
(NMSSM). We calculate their production cross sections and decay branching
ratios, comparing these with simulation results from existing reference. 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. We find that at a
collider with 3 ab^-1 of integrated luminosity, the potential for detecting
heavy Higgs bosons varies significantly with their mass and tanβ. Heavy
Higgs bosons below 2 TeV are within the testable range, while those heavier
than 7 TeV fall below the exclusion and discovery thresholds, rendering them
undetectable. For masses between 2 and 7 TeV, heavy Higgs bosons with
tanβ less than 20 can be detected, whereas those with tanβ
greater than 20 are beyond the current discovery or exclusion capabilities.
