Lepton flavor violation and lepton dipole moments in SUSY low scale seesaw models

Type: Lepton Flavour Violation and Neutrinos
Track: Lepton Flavour Violation and Neutrinos


The analysis of the leptonic lepton flavour violation (LFV) processes and lepton dipole moments in low scale seesaw models of minimally extended minimal supergravity (SUGRA) is presented. Minimal extension of the minimal SUGRA framework for MSSM is achieved adding a CP violating phase only in the soft SUSY breking trilinear couplings for right sneutrinos, $A_\nu$. For the LFV processes two new box helicity amplitudes, not considered before, were found. Numerical results show dominance of the soft SUSY breaking Z-boson and heavy neutrino box amplitudes, opposed to the photon-penguin dominance in the high scale seesaw models. The muon anomalous magnetic moment ($a_\mu) anomaly $\Delta a_\mu$ cannot be explained by the presence of the heavy neutrinos and sneutrinos, since their contribution to $a_\mu$ is too small to explain $\Delta a_\mu$. At the one loop level the electric dipole moment (EDM) of the electron ($d_e$) depends strongly on $A_\nu$ phase. It is equal zero for zero phase and achieves values comparable to the experimental $d_e$ upper bounds for the maximal CP phase.
