Abstract

We introduce a parity RF to introduce naturally small masses for the first family members and in particular almost massless u quark toward the strong CP solution. We also discuss the phenomenological implications of this model on the proton decay and the neutrino mass. Furthermore, it is possible to embed this RF parity to local U(1)R gauge symmetry.
