Abstract

In this article, after a short introduction, grand unified S U(5)×S U(5)′ model augmented by D 2 parity has been discussed. The latter turns out to be important for phenomenology. Specific pattern of the GUT symmetry breaking causes new strong dynamics at low energies. Consequently, the Standard Model leptons, along with right-handed /sterile neutrinos, come out as composite states. Issues of the gauge coupling unification, generation of the charged fermion and neutrino masses will be presented. Also, various phenomenological implications and constraints will be discussed.

As was shown [8], in specific circumstances, within GUTs one can suppress or even completely rotate away the d=6 nucleon decays
