Abstract

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.

在100 TeV强子对撞机上探索重希格斯玻色子与半约束的下至最小超对称标准模型*
在这项研究中,我们探讨了在半约束的下至最小超对称标准模型中,100 TeV 强子对撞机通道中重希格斯玻色子的可探测性。我们计算了它们的产生截面和衰变分支比,并与文献中的模拟结果进行了比较。我们的研究重点是以重双特为主的CP偶合希格斯粒子H和CP非偶合希格斯粒子A,其质量限值设定在10 TeV以下,以确保可探测性。在综合光度为 3 ab 的对撞机上,探测到重希格斯玻色子的可能性随其质量和质量的不同而有很大差异。 质量低于 2 TeV 的重希格斯玻色子在可检测范围之内,而重于 7 TeV 的则低于排除和发现阈值,因而无法探测到。对于质量在 2 到 7 TeV 之间的重希格斯玻色子,质量小于 20 的可以检测到,而质量大于 20 的则超出了目前的发现或排除能力。
