We study the effect of SUSY phases on rare decays of leptons and on their magnetic and electric dipole moments. We consider the most general mass matrices for sleptons within the MSSM including left--right mixing, flavour mixing and complex phases. We show that the phases also affect CP even observables. Moreover, we demonstrate that contrary to common belief the phase of mu can be large even for slepton masses as small as 200 GeV provided the lepton flavour violating parameters are complex.

The paper

Original abstract

We study the effect of SUSY phases on rare decays of leptons and on their magnetic and electric dipole moments. We consider the most general mass matrices for sleptons within the MSSM including left--right mixing, flavour mixing and complex phases. We show that the phases also affect CP even observables. Moreover, we demonstrate that contrary to common belief the phase of mu can be large even for slepton masses as small as 200 GeV provided the lepton flavour violating parameters are complex.

Untagged B -> X_(s+d) gamma CP asymmetry as a probe for new physics
hep-ph 2003-12 conditional novelty 6.0 of 10

The untagged B -> X_(s+d) gamma CP asymmetry stays below about 2% in minimal-flavour-violating supersymmetry even with new phases, but can reach plus or minus 10% if new physics enters the b -> s dipole operators alone.
SPheno 3.1: extensions including flavour, CP-phases and models beyond the MSSM

SPheno 3.1 adds flavour mixing, CP phases, R-parity violation, seesaw models, and low-energy observables to the SPheno SUSY spectrum calculator, documented through extended SLHA input and output blocks.

New sources of lepton flavor violation arise from supersymmetry (susy) breaking contributions causing intergenerational slepton mixing, for earlier works, see e.g., [ref] , and [ref] for flavor non-universal but diagonal effects.
