Abstract
We analyze the effects of CP violating phases in a fully left-right
extension of the minimal
supersymmetric model. These phases appear from both the heavy and light
neutrino sectors: two CKM-type phases, and four Majorana phases. We
study observable effects of these phases in lepton
flavor violating decays, such as the T-odd asymmetry in
, as well as
in the leptonic electric dipole moments. We impose the experimental
constraints from the mixing of light neutrinos and
analyze cases in which the heavy and light neutrinos are either
degenerate, or hierarchical, and highlight the dominant
variables in each case. CP violating phases in both the heavy and
light neutrino sectors of the
left-right supersymmetric model have unique features which, if tested
in the charged lepton sector, may distinguish the
model from other supersymmetric scenarios.
