Quantization of Superstrings in Ramond-Ramond Backgrounds

arXiv:hep-th/9910145 · doi:10.1103/PhysRevD.63.026004

Abstract

We present a perturbative study of Ramond-Ramond backgrounds in the NSR formalism. We show how to perform sigma-model computations and discuss in detail the structure of the BRST charge and picture-changing operators. Contact terms play a vital role in the analysis. We also give evidence for a two loop non-renormalization theorem for the background beta functions.
