Renormalization of the Planck mass for type II superstrings on symmetric orbifolds

Abstract

We compute the one-loop renormalization of the Planck mass for type II string theories compactified to four dimensions on symmetric orbifolds that preserve $\mathcal{N}=2$ supersymmetry. Depending on the orbifold, the effect can be as large as to compete with the standard tree-level value.
