Abstract

We analyze the lepton flavor violation processes μe\mu-e conversion, liljγl_i\rightarrow l_j\gamma and li3ljl_i\rightarrow 3l_j in framework of the Standard Model (SM) extended with inverse seesaw mechanism, as a function of η~=1Det(U~PMNS)\tilde{\eta} = 1 -|Det(\tilde {U}_{PMNS})| that parameterizes the departure from unitary of the light neutrino mixing sub-matrix U~PMNS\tilde {U}_{PMNS}. In a wide range of η~\tilde{\eta}, the predictions on the μe\mu-e conversion rates and the branching ratio of μeγ\mu\rightarrow e\gamma are sizeable to be compatible with the experimental upper limits or future experimental sensitivities. For large scale of η~\tilde{\eta}, the predictions on branching ratios of other lepton flavor processes can also be reach the experimental upper limits or future experimental sensitivities. The value of η~\tilde{\eta} depends on the determinant of the Majorana mass term MμM_{\mu}. Finally, searching for lepton flavor violation processes in experiment provides us more opportunities for the searches of seesaw nature of the neutrino masses.
