A radiatively induced neutrino mass model with hidden local U(1) and LFV processes ? _i → ? _j γ, μ → eZ′ and μe → ee

摘要

A bstract We investigate a model based on hidden U(1)_( X )gauge symmetry in which neutrino mass is induced at one-loop level by effects of interactions among particles in hidden sector and the Standard Model leptons. Neutrino mass generation is also associated with U(1)_( X )breaking scale which is taken to be low to suppress neutrino mass. Then we formulate neutrino mass matrix, lepton flavor violating processes and muon g ? 2 which are induced via interactions among Standard Model leptons and particles in U(1)_( X )hidden sector that can be sizable in our scenario. Carrying our numerical analysis, we show expected ratios for these processes when generated neutrino mass matrix can fit the neutrino data.
