Abstract
We report on tests of the AdS-CFT correspondence that are made possible by complete knowledge of the Kaluza-Klein mass spectrum of type IIB supergravity on AdS 5 × T 11 with T 11 = SU (2)2 /U (1). After briefly discussing general multiplet shortening conditions in SU (2,2|1) and PSU (2,2|4), we compare various types of short SU (2,2|1) supermultiplets on AdS 5 and different families of boundary operators with protected dimensions. The supergravity analysis predicts the occurrence in the SCFT at leading order in N and gs N , of extra towers of long multiplets whose dimensions are rational but not protected by supersymmetry.Keywords
