Singular Yukawa and gauge couplings in d=4 Heterotic String Vacua
arXiv:hep-th/9707212 · doi:10.1016/S0550-3213(97)00729-3
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.
