1/8 BPS states in AdS/CFT

We study a class of exact supersymmetric solutions of type IIB Supergravity. They have an SO(4) × SU(2) × U(1) isometry and preserve generically 4 of the 32 supersymmetries of the theory. Asymptotically AdS5 × S5 solutions in this class are dual to 1/8 BPS chiral operators which preserve the same symmetries in the = 4 SYM theory. They are parametrized by a set of four functions that satisfy certain differential equations. We analyze the solutions to these equations in a large radius asymptotic expansion: they carry charges with respect to two U(1) KK gauge fields and their mass saturates the expected BPS bound.
