The spectrum of IIB supergravity on AdS_5 x S^5/Z_3 and a 1/N^2 test of
AdS/CFT [PDF]
Arash A. Ardehali, James T. Liu, Phillip SzepietowskiWe present the complete Kaluza-Klein spectrum resulting from the compactification of IIB supergravity on S^5/Z_3. Knowledge of this spectrum allows us to perform a holographic computation of the difference of central charges c-a of the dual SU(N)^3 quiver gauge theory. We find the numerical value c-a=3/16, in exact agreement with the field theory result.View original: http://arxiv.org/abs/1304.1540
