Abstract

We study the mixing among different generations of massive neutrino fields in a $S U (2)_{L} \times S U (2)_{R} \times U (1)_{Y}$ gauge theory which includes Majorana and Dirac mass terms in the Yukawa sector. Parity can be spontaneously broken at a scale $v_{R} ≃ 1 0^{3} - 1 0^{4}$ GeV. We discuss about possible candidates for the Yukawa coupling matrices and we found that the model can accommodate a consistent pattern for neutral fermion masses as well as neutrino oscillations. The left and right sectors can be connected by a new neutral current.
