论文摘要
我们分析了违反的Lepton风味损失$τ\ rightarrow pl $（$ p =π，η，η'; \; \; \; l = e，μ$）在最小的R-对称超对称标准模型的情况下。分支比率br $（τ\ rightarrow p e）$和br $（τ\ rightarrowpμ）$的预测受质量插入参数的影响$δ^{13} $和$Δ^{23} $。这些参数受到分支比率BR（$τ\ rightarrow E（μ）γ$）和BR（$τ\ rightarrow 3E（μ）$）的实验界限的约束。结果显示，$ z $企鹅在参数空间的大区域中占据了BR（$τ\ rightarrow pl $）的预测。 BR的分支比率（$τ\ rightarrow pl $）至少被预测为五个数量级，比当前的实验边界小，比未来的实验灵敏度小三个数量级。
We analyze the lepton flavor violating decays $τ\rightarrow Pl$ ($P=π,η,η';\;l=e,μ$) in the scenario of the minimal R-symmetric supersymmetric standard model. The prediction on the branching ratios BR$(τ\rightarrow P e)$ and BR$(τ\rightarrow P μ)$ is affected by the mass insertion parameters $δ^{13}$ and $δ^{23}$, respectively. These parameters are constrained by the experimental bounds on the branching ratios BR($τ\rightarrow e (μ) γ$) and BR($τ\rightarrow 3e(μ)$). The result shows $Z$ penguin dominates the prediction on BR($τ\rightarrow Pl$) in a large region of the parameter space. The branching ratios for BR($τ\rightarrow Pl$) are predicted to be, at least, five orders of magnitude smaller than present experimental bounds and three orders of magnitude smaller than future experimental sensitivities.
