These wormholes can be inserted into $AdS_3 \times S^3 \times T^4$ backgrounds, which have a well-defined CFT dual. AdS/CFT duality then suggests that the wormhole solutions cannot be interpreted using $α$ parameters as originally suggested by Coleman.18 pages. ver. 2: typos corrected, references addedHigh Energy Physics - TheoryEuclidean Wormholes in String Theorytext
