Singular Yukawa and gauge couplings in d = 4 heterotic string vacua
Abstract
In this paper we discuss the singularities in the Yukawa and gauge couplings of N = 1 compactifications of the SO(32) heterotic string in four space-time dimensions. Such singularities can arise from the strong coupling dynamics of a confined non-perturbative gauge group.
