Extracting the CP-violating phases of trilinear R-parity violating couplings from μ→eee

It has recently been shown that by measuring the transverse polarizations of the final particles in μ+→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+→e+e−e+ process can take place at a tree level. We demonstrate how a combined analysis of the angular distribution of the emitted electrons and their transverse polarization can determine the CP-violating phases of the trilinear R-parity violating Yukawa couplings.
