摘要:

在标准模型的最小超对称扩展(MSSM)的背景下,我们重新分析了寻找更重的CP-偶$H$和CP-奇$A$中性希格斯玻色子在大型强子对撞机的胶子融合机制的生产和他们的衰变到规范和更轻的$h$玻色子和顶夸克对。我们表明,只有当考虑这些过程,一个可以完全覆盖整个参数空间的希格斯部门的模型。事实上,它们对低$\tanβ$和高希格斯质量范围敏感,补充了传统的对衰减成$τ$ -轻子对的高质量共振的搜索,这些轻子对对大的和中等的$\tanβ$区域敏感。在探测完整的$[\tanβ, M_A]$ MSSM参数空间在LHC的前一阶段和即将到来的阶段的各种渠道的互补性说明了在最近提出的一个简单的和模型独立的方法为希格斯部门,$h$ MSSM,我们也在本文中完善。

英文摘要:

In the context of the Minimal Supersymmetric extension of the Standard Model (MSSM), we reanalyze the search for the heavier CP-even $H$ and CP-odd $A$ neutral Higgs bosons at the LHC in their production in the gluon-fusion mechanism and their decays into gauge and lighter $h$ bosons and into top quark pairs. We show that only when considering these processes, that one can fully cover the entire parameter space of the Higgs sector of the model. Indeed, they are sensitive to the low $\tanβ$ and high Higgs mass ranges, complementing the traditional searches for high mass resonances decaying into $τ$-lepton pairs which are instead sensitive to the large and moderate $\tanβ$ regions. The complementarity of the various channels in the probing of the complete $[\tanβ, M_A]$ MSSM parameter space at the previous and upcoming phases of the LHC is illustrated in a recently proposed simple and model independent approach for the Higgs sector, the $h$MSSM, that we also refine in this paper.
