Gravitational Dressing of N=2 Sigma-Models Beyond Leading Order

High Energy Physics - Theory 2009-10-30 v1

Abstract

We study the beta-function of the N=2 sigma-model coupled to N=2 induced supergravity. We compute corrections to first order in the semiclassical limit, cc \to -\infty, beyond one-loop in the matter fields. As compared to the corresponding bosonic, metric sigma-model calculation, we find new types of contributions arising from the dilaton coupling automatically accounted for, once the K\"ahler potential is coupled to N=2 supergravity.
