LEPTON FLAVOR VIOLATION IN INVERSE SEESAW MODEL

Abstract

We analyze the lepton flavor violation processes μ-e conversion, li→ljγ and li→3lj in framework of the Standard Model (SM) extended with inverse seesaw mechanism, as a function of [Formula: see text] that parametrizes the departure from unitary of the light neutrino mixing sub-matrix [Formula: see text]. In a wide range of [Formula: see text], the predictions on the μ-e conversion rates and the branching ratio of μ→eγ are sizeable to be compatible with the experimental upper limits or future experimental sensitivities. For large scale of [Formula: see text], the predictions on branching ratios of other lepton flavor processes can also reach the experimental upper limits or future experimental sensitivities. The value of [Formula: see text] depends on the determinant of the Majorana mass term Mμ. Finally, searching for lepton flavor violation processes in experiment provides us more opportunities for the searches of seesaw nature of the neutrino masses.
