Abstract

The spectrum of IIB supergravity on AdS5 × S5 contains a number of bound states described by long
double-trace multiplets in N ¼ 4 super Yang-Mills theory at large ‘t Hooft coupling. At large N these states
are degenerate and to obtain their anomalous dimensions as expansions in 1
N2 one has to solve a mixing
problem. We conjecture a formula for the leading anomalous dimensions of all long double-trace operators
which exhibits a large residual degeneracy whose structure we describe. Our formula can be related to
conformal Casimir operators which arise in the structure of leading discontinuities of supergravity loop
corrections to four-point correlators of half-BPS operators.
