Superconformal field theories from IIB spectroscopy on AdS(5) x T-11

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 supergravi ty on AdS(5) x T-11 with T-11 = SU(2)(2)/U(1). After briefly discussing gen eral multiplet shortening conditions in SU(2, 2\1) and PSU(2, 2\4), we comp are various types of short SU(2, 211) supermultiplets on AdS5 and different families of boundary operators with protected dimensions. The supergravity analysis predicts the occurrence in the SCFT at leading order in N and g(s )N, of extra towers of long multiplets whose dimensions are rational but no t protected by supersymmetry.
