Conformal Field Theory of AdS Background with Ramond-Ramond Flux

TL;DR

This paper reviews a superstring quantization formalism with six-dimensional supersymmetry and applies it to AdS_3 x S^3 backgrounds with Ramond-Ramond flux, resulting in a conformal field theory based on a supergroup sigma model.

Contribution

It introduces a manifestly supersymmetric superstring quantization approach and models AdS_3 x S^3 backgrounds with a supergroup sigma model.

Findings

Develops a conformal field theory description for AdS_3 x S^3 with RR flux.

Utilizes a supergroup sigma model based on SU'(2|2).

Provides a framework for analyzing superstring backgrounds with RR flux.

Abstract

We review a formalism of superstring quantization with manifest six-dimensional spacetime supersymmetry, and apply it to AdS_3 x S^3 backgrounds with Ramond-Ramond flux. The resulting description is a conformal field theory based on a sigma model whose target space is a certain supergroup SU'(2|2).
