Abstract
We discuss radiative neutrino mass models with a general lepton flavor dependent U(1) gauge symmetry. The scotogenic model is adopted for neutrino mass generation in which Z2 odd singlet fermions and an inert scalar doublet are introduced. A lepton flavor dependent local U(1) symmetry is applied to realize two-zero texture of a Majorana mass matrix of Z2 odd singlet fermions where we explore minimal construction choosing U(1) charges of the standard model fermions and singlet fermions. Then we investigate neutrino mass matrix and show some predictions for constructed models, and discuss some phenomenological implications.
