Threshold effects in open-string theory
arXiv:hep-th/9605028 · doi:10.1016/0550-3213(96)00332-X
Abstract
We analyze the one-loop effective gauge-field action in -orbifold compactifications of type-I theory. We show how, for non-abelian group factors, the threshold effects are ultraviolet finite though given entirely by a six-dimensional field theory expression.
