从$μ\to eee$中提取三线性R宇称破坏耦合的CP破坏相位
Extracting the CP-violating phases of trilinear R-parity violating couplings from $μ\to eee$
摘要：
最近已经表明，通过测量$μ^- \to e^- e^+ e^-$中最终粒子的横向偏振，可以提取导致这种衰减的有效耦合的相位信息。我们研究这种可能性的上下文中的R-奇偶违反最小超对称标准模型（MSSM）中的$μ^- \to e^- e^+e^-$过程可以发生在树的水平。我们演示了如何结合分析的角度分布的发射的正电子和它们的横向偏振可以确定的CP违反三线性R-宇称违反汤川耦合相。
英文摘要：
It has recently been shown that by measuring the transverse polarizations of the final particles in $μ^- \to e^- e^+ e^-$, it is possible to extract information on the phases of the effective couplings leading to this decay. We examine this possibility within the context of R-parity violating Minimal Supersymmetric Standard Model (MSSM) in which the $μ^- \to e^- e^+e^-$ process can take place at a tree level. We demonstrate how a combined analysis of the angular distribution of the emitted positrons and their transverse polarization can determine the CP-violating phases of the trilinear R-parity violating Yukawa couplings.
