Selection Rules for Nonrenormalizable Couplings in Superstring Theories

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

We study nonrenormalizable coupling terms in ZNZ_N orbifold models. Nontrivial selection rules of couplings are provided and cannot be understood in terms of a simple symmetry of effective field theories. We also discuss phenomenological implications of theses selection rules for the quark mass matrices.
