论文摘要
在这项工作中，我们分析并展示了探索最小超对称标准模型（MSSM）的扩展希格斯领域的可能策略。特别是，我们专注于巨大的希格斯腐烂到electroweakinos。在考虑到13 TEV LHC搜索超对称颗粒和现象学约束之后，我们将HIGG分析到允许的MSSM参数空间中的Electroweakino衰变，例如风味物理学，HIGGS测量和暗物质约束。我们探索了这些希格斯衰减的一些新颖方面。 Higgs到Electroweakino衰减产生的最终状态将具有标准模型以及LHC的直接electroweakino生产产生的背景。我们证明了希格斯之间的显式运动学差异，这些运动学差异和相关背景。此外，我们证明了一些特定的示例点，高光度LHC（HL-LHC）运行的优化分析搜索策略。最后，我们评论了重型希格斯（Higgs）可能衰减到异国最终状态的可能搜索策略，在那里，最轻的夏金诺（Chargino）长期以来一直居住，并导致LHC的消失轨道。
In this work, we analyse and demonstrate possible strategies to explore extended Higgs sector of the Minimal Supersymmetric Standard Model (MSSM). In particular we concentrate on heavy Higgs decays to electroweakinos. We analyse the Higgs to electroweakino decays in the allowed MSSM parameter space after taking into account 13 TeV LHC searches for supersymmetric particles and phenomenological constraints such as flavour physics, Higgs measurements and dark matter constraints. We explore some novel aspects of these Higgs decays. The final states resulting from Higgs to electroweakino decays will have backgrounds arising from the Standard Model as well as direct electroweakino production at the LHC. We demonstrate explicit kinematical differences between Higgs to electroweakino decays and associated backgrounds. Furthermore, we demonstrate for a few specific example points, optimised analysis search strategies at the high luminosity LHC (HL-LHC) run. Finally, we comment on possible search strategies for heavy Higgs decays to exotic final states, where the lightest chargino is long lived and leads to a disappearing track at the LHC.
