A window on the CP-violating phases of MSSM from lepton flavor violating processes

It has recently been shown that by measuring the transverse polarization of the final particles in the LFV processes mu -> c gamma, mu -> ccc and mu N -> cN, one can derive information on the CP-violating phases of the underlying theory. We derive formulas for the transverse polarization of the final particles in terms of the couplings of the effective potential leading to these processes. We then study the dependence of the polarizations of e and gamma in the mu -> e gamma and mu N -> eN on the parameters of the Minimal Supersymmetric Standard Model (MSSM). We show that combining the information on various observables in the mu -> e gamma and mu N -> eN search experiments with the information on the electric dipole moment of the electron can help us to solve the degeneracies in parameter space and to determine the values of certain phases.
