标题： Momentum distribution of the electron pair from the charged lepton flavor violating process $μ^-e^-\to e^-e^-$ in muonic atoms with a polarized muon

摘要： μ子原子中的$\mu^-e^-\to e^-e^-$过程是研究带电轻子味违反（CLFV）的有前途的探针。 我们研究了原子束缚态中极化μ子产生的电子的角度分布。 通过使用在有限核电荷分布的库仑相互作用下的轻子波函数来分析电子的宇称破坏不对称分布。 发现电子的不对称参数对CLFV相互作用的手性结构以及接触/光子相互作用非常敏感。 因此，结合我们在以前工作中研究的衰变率的原子序数依赖性，来自极化μ子的电子的角度分布应该是一个非常有用的工具，用于约束超出标准模型的理论模型。 显示英文摘要

摘要： The $\mu^-e^-\to e^-e^-$ process in a muonic atom is one of the promising probes to study the charged lepton flavor violation (CLFV). We have investigated the angular distribution of electrons from the polarized muon of the atomic bound state. The parity violating asymmetric distribution of electrons is analyzed by using lepton wave functions under the Coulomb interaction of a finite nuclear charge distribution. It is found that the asymmetry parameters of electrons are very sensitive to the chiral structure of the CLFV interaction and the contact/photonic interaction. Therefore, together with the atomic number dependence of the decay rate studied in our previous work, the angular distribution of electrons from a polarized muon should be a very useful tool to constrain the model beyond the standard model.
