AI 中文摘要
备用方案模型由阿拉纳赫等人于2023年提出，可解释费米子质量谱的一些总体特征，还影响涉及 $b \rightarrow s$ 夸克味转变的各种可观测量预测。该模型预测了一个新的 TeV 尺度的 $Z^{\prime}$，它衰变成各种不同的末态。通过重新分析大型强子对撞机（LHC）对 $Z^{\prime}$ 的几次直接搜索，以及使用Contur根据标准模型中预测非零的各种微分截面的展开测量来测试该模型，我们限制了模型的可行参数空间。我们划定了当前LHC数据排除的参数空间区域，并估计了高亮度LHC的预计探测范围。
英文摘要
The Plan B Model was proposed by Allanach et al. (2023) and explains some gross features of the fermion mass spectrum. It also affects the predictions of various observables involving the $b \rightarrow s$ quark-flavour transition. The model predicts a new TeV-scale $Z^{\prime}$ which decays into various different final states. We constrain the viable parameter space of the model by re-casting several LHC direct searches for the $Z^{\prime}$ in addition to using Contur to test the model against unfolded measurements of various differential cross sections that are predicted to be non-zero in the Standard Model. We delineate the regions of parameter space that are excluded by current LHC data, and estimate the projected reach of the high luminosity LHC.
