| Popis: | We analyze the lepton flavor violation processes $\mu-e$ conversion, $l_i\rightarrow l_j\gamma$ and $l_i\rightarrow 3l_j$ in framework of the Standard Model (SM) extended with inverse seesaw mechanism, as a function of $\tilde{\eta} = 1 -|Det(\tilde {U}_{PMNS})|$ that parameterizes the departure from unitary of the light neutrino mixing sub-matrix $\tilde {U}_{PMNS}$. In a wide range of $\tilde{\eta}$, the predictions on the $\mu-e$ conversion rates and the branching ratio of $\mu\rightarrow e\gamma$ are sizeable to be compatible with the experimental upper limits or future experimental sensitivities. For large scale of $\tilde{\eta}$, 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 $\tilde{\eta}$ depends on the determinant of the Majorana mass term $M_{\mu}$. Finally, searching for lepton flavor violation processes in experiment provides us more opportunities for the searches of seesaw nature of the neutrino masses. Comment: 13 pages, 7 figures |
