Abstract: (WSP)

We present a left-right symmetric model in which small and finite Dirac neutrino masses are generated as two-loop radiative corrections. Typical masses of the order 10−2eV, 1 eV and 102eV are obtained for νe, νμ and ντ, respectively. The model also features a generalized seesaw mechanism for the charged fermions which is achieved by the inclusion of heavy charged singlet fermions.
