论文摘要
我们分析了最近在$ r $ $ $ $ - 米斯森的充电和中性稀有衰减中违反$ r $ $ - 违反超对称方案的罕见衰减的Lepton风味普遍性的提示。以简单性和最低限度的启发，我们早些时候假定第三代超级零部队是最轻的（称为“ RPV3”），并明确表明它可以保留量规耦合统一，并且当然具有自然解决HIGGS辐射稳定性的常用属性。在这里，我们表明$ r_ {d^{（*）}} $和$ r_ {k^{（*）}} $ theaver Anomalies可以在此RPV3框架中解决。有趣的是，这种情况也可能能够容纳另外两个看似不同的异常情况，即Muon $（G-2）$的长期差异，以及最近发生的异常正在进行的超高能量Anita事件。基于对称参数，我们考虑相关的RPV3耦合的三个不同基准点，并雕刻出参数空间的区域，这些区域可以同时解释所有这些异常。我们发现，鉴于在最小模型参数空间上的精度低能和高能量实验约束，因此存在这种重叠区域。在这种理论结构中所需的第三代超级参与者都在1-10 TEV范围内，可在LHC和/或下一代强子对撞机上访问。我们还讨论了Tau-Lepton的Lepton-Fravor-Fravor-violation腐烂的一些可测试预测，以及当前和未来的$ b $ - 物理实验（例如LHCB和Belle II）的$ B $ -Mesons。还讨论了诸如LHC之类的高$ P_T $制度中风味异常的互补测试。
We analyze the recent hints of lepton flavor universality violation in both charged-current and neutral-current rare decays of $B$-mesons in an $R$-parity violating supersymmetric scenario. Motivated by simplicity and minimality, we had earlier postulated the third-generation superpartners to be the lightest (calling the scenario "RPV3") and explicitly showed that it preserves gauge coupling unification and of course has the usual attribute of naturally addressing the Higgs radiative stability. Here we show that both $R_{D^{(*)}}$ and $R_{K^{(*)}}$ flavor anomalies can be addressed in this RPV3 framework. Interestingly, this scenario may also be able to accommodate two other seemingly disparate anomalies, namely, the longstanding discrepancy in the muon $(g-2)$, as well as the recent anomalous upgoing ultra-high energy ANITA events. Based on symmetry arguments, we consider three different benchmark points for the relevant RPV3 couplings and carve out the regions of parameter space where all (or some) of these anomalies can be simultaneously explained. We find it remarkable that such overlap regions exist, given the plethora of precision low-energy and high-energy experimental constraints on the minimal model parameter space. The third-generation superpartners needed in this theoretical construction are all in the 1-10 TeV range, accessible at the LHC and/or next-generation hadron collider. We also discuss some testable predictions for the lepton-flavor-violating decays of the tau-lepton and $B$-mesons for the current and future $B$-physics experiments, such as LHCb and Belle II. Complementary tests of the flavor anomalies in the high-$p_T$ regime in collider experiments such as the LHC are also discussed.
