Abstract

We present a model based on the gauge group SU(2)_L× SU(2)_R × SU(4)_C with gauge couplings that are found to be unified at a scale near the string unification scale. This model breaks to the MSSM at an intermediate scale which is instrumental in producing a neutrino in a mass range that can serve as hot dark matter and can also solve the strong CP problem via a harmless invisible axion.
