Supersymmetric Unification without Proton Decay

Abstract

We present a supersymmetric grand unification scheme based on the gauge group SU(3)_c X SU(3)_L X SU(3)_R in which the proton and the lightest supersymmetric particle are stable, neutrinos are necessarily massive, and the observed baryon asymmetry originates in the lepton sector. Such models are also consistent with the measured value of sin^2Θ_W as well as unification of the gauge couplings.
