Radiative neutrino mass in an alternative U(1)B−L gauge symmetry.

Abstract We propose a neutrino model in which neutrino masses are generated at one loop level and three right-handed fermions have non-trivial charges under U (1) B − L gauge symmetry in no conflict with anomaly cancellation. After the spontaneously symmetry breaking, a remnant Z 2 symmetry is induced and plays an role in assuring the stability of dark matter candidate. [ABSTRACT FROM AUTHOR]
