We observe that the pp wave limit of AdS5£M 5 compactiflcations of type- IIB string theory is universal, and maximally supersymmetric, as long as M 5 is smooth and preserves some supersymmetry. We investigate a speciflc case, M 5 = T 1;1 . The dualN = 1 SCFT, describing D3-branes at a conifold singularity, has operators that we identify with the oscillators of the light-cone string in the universal pp wave background. The correspondence is remarkable in that it relies on the exact spectrum of anomalous dimensions in this CFT, along with the existence of certain exceptional series of operators whose dimensions are protected only in the limit of large 't Hooft coupling. We also brie∞y examine the singular case M 5 = S 5 =Z2, for which the pp wave background becomes a Z2 orbifold of the maximally supersymmetric background by re∞ection of 4 transverse coordinates. We flnd operators in the correspondingN = 2 SCFT with the right properties to describe both the untwisted and the twisted sectors of the closed string.

Branes in AdS and pp-wave spacetimes (2002, background): “We explicitly prove that these embeddings are supersymmetric by showing that the kappa symmetry projections are compatible with half of the target space Killing spinors and argue that all these cases lead to AdS/dCFT dualities involving a CFT with a defect.”
