Wrapped fivebranes redux

Abstract

Abstract The near-horizon region of Neveu-Schwarz fivebranes provides interesting examples of gauge/gravity duality. We revisit the structure of wrapped and/or intersecting fivebranes using the tools of null-gauged WZW models in worldsheet string theory, revealing the effective geometry of the fivebrane throat in a variety of examples. Variant gaugings yield linear dilaton fivebrane throats with AdS 3 caps, providing a wealth of information about the near-BPS structure of the corresponding spacetime CFT duals.
