Quantization of superstrings in Ramond-Ramond backgrounds

David Berenstein, Robert G. Leigh

Research output: Contribution to journalArticlepeer-review


We present a perturbative study of Ramond-Ramond backgrounds in the NSR formalism. We show how to perform σ-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.
