Description |
We study conical defect geometries in the SL(N,R) x SL(N,R) (and SL(N, C)) Chern-Simons formulation of higher spin gauge theories in AdS3. We argue that (for N >= 4) there are special values of the deficit angle for which these geometries are actually smooth configurations of the underlying theory. We also exhibit a gauge in which these geometries can be viewed as wormholes interpolating between two distinct asymptotically AdS3 spacetimes. Remarkably, the spectrum of smooth SL(N, C) solutions, after an appropriate analytic continuation, exactly matches that of the so-called ``light primaries'' in the minimal model WN CFTs at finite N. This gives a candidate bulk interpretation of the latter states in the holographic duality proposed by Gaberdiel and Gopakumar. |
