论文摘要
除了标准模型(SM)之外,其他Higgs玻色子的预测是产生扩展的Higgs部门的关键特征之一。我们评估了高光度(HL)单独运行的大型强子对撞机(LHC)的敏感性,并与可能的未来国际线性对撞机(ILC)结合使用,以探测重型中性中性希格斯玻色子。我们采用最小的超对称标准模型(MSSM)作为框架,并假设光CP-even MSSM Higgs玻色子是在125 GEV处观察到的Higgs玻色子。我们讨论了由于在125 GEV处检测到的信号速率以及在$τ^+τ^ - $,$ b \ bar {b} $和di-higgs($ hh $ hh $)最终状态的最终搜索中,对检测到的信号速率的精确测量以及直接搜索新的重型希格斯玻色子而产生的约束。在这种情况下,提出了$ b \ bar {b} $ Channel中用于重型希格斯的新基准方案。对于未来HL-LHC和ILC的HIGGS利率测量值,研究了两种不同的情况,即未来利率测量与SM预测一致的情况,而利率与MSSM HIGGS部门可能实现的预测相一致的情况。
The prediction of additional Higgs bosons is one of the key features of physics beyond the Standard Model (SM) that gives rise to an extended Higgs sector. We assess the sensitivity of the Large Hadron Collider (LHC) in the high luminosity (HL) run alone and in combination with a possible future International Linear Collider (ILC) to probe heavy neutral Higgs bosons. We employ the Minimal Supersymmetric Standard Model (MSSM) as a framework and assume the light CP-even MSSM Higgs boson to be the Higgs boson observed at 125 GeV. We discuss the constraints on the MSSM parameter space arising from the precision measurements of the rates of the detected signal at 125 GeV and from direct searches for new heavy Higgs bosons in the $τ^+τ^-$, $b\bar{b}$ and di-Higgs ($hh$) final states. A new benchmark scenario for heavy Higgs searches in the $b\bar{b}$ channel is proposed in this context. For the future Higgs rate measurements at the HL-LHC and ILC two different scenarios are investigated, namely the case where the future rate measurements agree with the SM prediction and the case where the rates agree with the predictions of possible realizations of the MSSM Higgs sector in nature.
