Quantization of the Type II Superstring in a Curved Six-Dimensional Background
arXiv:hep-th/9908041 · doi:10.1016/S0550-3213(99)00690-2
Abstract
A sigma model action with N=2 D=6 superspace variables is constructed for the Type II superstring compactified to six curved dimensions with Ramond-Ramond flux. The action can be quantized since the sigma model is linear when the six-dimensional spacetime is flat. When the six-dimensional spacetime is $AdS_3\times S^3$, the action reduces to one found earlier with Vafa and Witten.
