Euclidean Wormholes in String Theory

Abstract

We show that toroidal compactification of type II string theory to six dimensions admits axionic euclidean wormhole solutions. These wormholes can be inserted into $Ad{S}_3\times S^3\times T^4$ backgrounds, which have a well-defined CFT dual. AdS/CFT duality then suggests that the wormhole solutions cannot be interpreted using $\alpha$ parameters as originally suggested by Coleman.
