String theory in magnetic monopole backgrounds Original Research Article

We discuss string propagation in the near-horizon geometry generated by Neveu-Schwarz fivebranes, Kaluza-Klein monopoles and fundamental strings. When the fivebranes and KK monopoles are wrapped around a compact four-manifold M, the geometry is AdS3 × S3/ZN × M and the space-time dynamics is expected to correspond to a local two-dimensional conformal field theory. We determine the moduli space of space-time CFTʹs, study the spectrum of the theory and compare the chiral primary operators obtained in string theory to supergravity expectations.
