在无$μ\to e γ$和$μ\to 3e$信号的情况下交叉检查$μ$ - $e$转换的方法
A way to crosscheck $μ$-$e$ conversion in the case of no signals of $μ\to e γ$ and $μ\to 3e$
摘要:
我们考虑这样一种情况,即发现了$μ$ - $e$转换信号,但永远找不到其它的带电轻子味违反过程,在这种情况下,我们需要其它的方法来证实$μ$ - $e$转换及其基础物理,而不需要常规的cLFV搜索.我们研究R-宇称破坏(RPV)超对称模型作为基准。我们简要回顾了我们感兴趣的情况下,实现RPV超对称模型与合理的设置,根据目前的理论/实验状态。我们专注于在LHC的外来对撞机签名($pp \to μ^- e^+$和$pp \to jj$)的其他方法。我们给出了$μ$ - $e$转化过程的分支比与这些过程的截面之间的相关性。这是第一次以图形方式显示相关性。给出了分支比和截面对RPV参数的依赖关系,并讨论了确定参数的可行性。
英文摘要:
We consider the case that $μ$-$e$ conversion signal is discovered but other charged lepton flavor violating (cLFV) processes will never be found. In such a case, we need other approaches to confirm the $μ$-$e$ conversion and its underlying physics without conventional cLFV searches. We study R-parity violating (RPV) SUSY models as a benchmark. We briefly review that our interesting case is realized in RPV SUSY models with reasonable settings according to current theoretical/experimental status. We focus on the exotic collider signatures at the LHC ($pp \to μ^- e^+$ and $pp \to jj$) as the other approaches. We show the correlations between the branching ratio of $μ$-$e$ conversion process and cross sections of these processes. It is first time that the correlations are graphically shown. We exhibit the RPV parameter dependence of the branching ratio and the cross sections, and discuss the feasibility to determine the parameters.
