论文摘要
我们在$ u（1）'$扩展的MSSM中研究了强子乘员的$ z'$现象学。我们选择一个具有僻静部门的$ U（1）'$型号，通过将三个额外的Singlet Superfield纳入该模型，可以解决Electroweak量表与为$ Z'$开发足够大的质量之间的张力。我们对生产进行了详细的分析，其次是腐烂，包括$ z'$ boson的超对称粒子，质量在4至5.2 TEV之间，特别强调了其可能的发现。我们选择与最新可用的实验数据和遗物密度约束一致的三种不同方案，并专注于带有两个瘦素，四个瘦素和六个瘦素的最终信号。包括来自两个，三个或四个矢量玻色子的过程的SM背景，我们表明观察$ z^\ prime $ boson的可能性对于14 TEV的HL-LHC不希望。虽然在27和100 TEV时，情况更加乐观，我们设计了可以观察到的特定基准方案。
We study $Z'$ phenomenology at hadron colliders in an $U(1)'$ extended MSSM. We choose a $U(1)'$ model with a secluded sector, where the tension between the electroweak scale and developing a large enough mass for $Z'$ is resolved by incorporating three additional singlet superfields into the model. We perform a detailed analysis of the production, followed by decays, including into supersymmetric particles, of a $Z'$ boson with mass between 4 and 5.2 TeV, with particular emphasis on its possible discovery. We select three different scenarios consistent with the latest available experimental data and relic density constraints, and concentrate on final signals with two leptons, four leptons and six leptons. Including the SM background from processes with two, three or four vector bosons, we show the likelihood of observing a $Z^\prime$ boson is not promising for the HL-LHC at 14 TeV. While at 27 and 100 TeV, the situation is more optimistic, and we devise specific benchmark scenarios which could be observed.
