String loop corrected hypermultiplet moduli spaces
Daniel Robles-Llana, Frank Saueressig, Stefan Vandoren

TL;DR
This paper determines the one-loop string corrections to hypermultiplet moduli spaces in type II string compactifications on Calabi-Yau threefolds, showing that higher loop corrections are absent due to a non-renormalization theorem.
Contribution
It provides a complete characterization of the one-loop corrected quaternion-Kahler moduli spaces using supersymmetry constraints and superspace techniques, establishing a non-renormalization result.
Findings
One-loop correction is explicitly determined.
Higher loop corrections are excluded by a non-renormalization theorem.
The moduli space is encoded in a single function.
Abstract
Using constraints from supersymmetry and string perturbation theory, we determine the string loop corrections to the hypermultiplet moduli space of type II strings compactified on a generic Calabi-Yau threefold. The corresponding quaternion-Kahler manifolds are completely encoded in terms of a single function. The latter receives a one-loop correction and, using superspace techniques, we argue for the existence of a non-renormalization theorem excluding higher loop contributions.
