Impact of CP-violating phases of Minimal Supersymmetric Standard Model on low energy experiment

Mr. Yaser Ayazi defend his thesis from IPM

 Abstract : As it is well-known, the general Minimal Supersymmetric Standard Model (MSSM) introduces new sources for Lepton Flavor Violation (LFV) as well as CP-violation. In this thesis, the possibility of cancelation between different contributions of CP-violating phases to $d_e$, $d_n$ and $d_{Hg}$ is reconsidered with special emphasis on the region that is phenomenologically interesting. We show that when both sources ( Lepton Flavor Violation sources and CPviolating phases) are present $d_e$, receives a contribution from the phase of the trilinear $A$-term of staus, $\phi_{A_\tau}$. We then study the dependence of the polarizations of $e$ and $\gamma$ in the $\mu \to e \gamma$ and $\mu N \to e N$ on the parameters of the MSSM.
