Neutrino Masses in Superstring Derived Standard--like Models

High Energy Physics - Theory 2011-02-09 v1

Abstract

We propose a new scenario in a class of superstring derived standard--like models that explains the suppression of the left--handed neutrino masses. Due to nonrenormalizable terms and the breaking of the U(1)ZU(1)_{Z^\prime} symmetry a generalized see--saw mechanism takes place. Contrary to the traditional see--saw mechanism in GUTs, the see--saw scale and the right--handed neutrino mass scale are suppressed relative to the U(1)ZU(1)_{Z^\prime} breaking scale.
