论文摘要
长期存在的Muon $(G-2)$异常,以及$ b $ - 米森衰减中的Lepton风味普遍性的持续提示,可能表明超出了标准模型(SM)的新物理。一个最小的$ r $ r $ -Parity-Parity-Parity超对称框架,带有轻度的第三代Sfermions(称为“ RPV3”)为这些风味异常提供了令人信服的解决方案,同时解决了SM的其他紧迫问题。我们为MUON $(G-2)$异常的解决方案提出了一种新的RPV3方案,该方案导致有趣的LHC信号为$μ^+μ^-τ^+τ^ - $最终状态。我们分析了Run-2 LHC多龙数据数据,以在这种情况下对Sneutrino质量的严格约束和相关的RPV耦合产生严格的约束。然后,我们提出了专门的选择策略,即使在现有数据集使用现有数据集的情况下,也可以改善界限。我们还表明,高光度LHC将完全覆盖其余的Muon $(G-2)$ - 首选参数空间,从而提供了对Muon $(G-2)$异常的强大独立测试。
The longstanding muon $(g-2)$ anomaly, as well as the persistent hints of lepton flavor universality violation in $B$-meson decays, could be signaling new physics beyond the Standard Model (SM). A minimal $R$-parity-violating supersymmetric framework with light third-generation sfermions (dubbed as 'RPV3') provides a compelling solution to these flavor anomalies, while simultaneously addressing other pressing issues of the SM. We propose a new RPV3 scenario for the solution of the muon $(g-2)$ anomaly, which leads to an interesting LHC signal of $μ^+μ^-τ^+τ^-$ final state. We analyze the Run-2 LHC multilepton data to derive stringent constraints on the sneutrino mass and the relevant RPV coupling in this scenario. We then propose dedicated selection strategies to improve the bound even with the existing dataset. We also show that the high-luminosity LHC will completely cover the remaining muon $(g-2)$-preferred parameter space, thus providing a robust, independent test of the muon $(g-2)$ anomaly.
