Description
We consider constraints on superstring theories compactified on Calabi-Yau manifolds arising from the proton lifetime, neutrino masses, sin2thetasub(w), and the requirement of perturbative unification. All possible low-energy gauge groups are studied with variable number of generations. Several three-generation models pose no immediate problem. Four-generation models need an intermediate scale. We suggest a natural mechanism to generate it. (orig.)
