Superstring Vertex Operators in an AdS_5 x S^5 Background

arXiv:hep-th/0009168 · doi:10.1016/S0550-3213(00)00697-0

Abstract

A quantizable action has recently been proposed for the superstring in an AdS_5 x S^5 background with Ramond-Ramond flux. In this paper, we construct physical vertex operators corresponding to on-shell fluctuations around the AdS_5 x S^5 background. The structure of these AdS_5 x S^5 vertex operators closely resembles the structure of the massless vertex operators in a flat background.
