Description
Maximally supersymmetric Yang-Mills theory in dimension d≠4 is perhaps the simplest non-conformal quantum field theory with a holographic gravity dual. Its large-N, strong-coupling BPS dynamics is captured by supergravity fluctuations around the D-brane solutions of string theory. After consistent truncation, and in the appropriate conformal frame, these solutions reduce to an AdS metric plus an active scalar, the dilaton, which breaks the scale invariance of AdS spacetime. In this talk, I will report recent progress in the computation of holographic correlators in this setup. I will argue that propagators in this type of background can be constructed by dimensionally reducing AdS propagators and explain how the 3pt-function of scalar operators in the dual strongly-coupled QFT follows from this simple fact.
