Abstract: (arXiv)

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.
