Description
In this talk we will review some new achievements about the computation of integrated correlators in 4d SCFTs, which possess a dual holographic interpretation in terms of string scattering amplitudes in presence of D-branes. In particular, we will concentrate on two setups: (i) a class of correlators in $\mathcal{N}=4$ SYM with heavy operators dual to semiclassical D3-brane giant graviton solutions; (ii) integrated correlators in special $\mathcal{N}=2$ SCFTs with fundamental and antisymmetric matter content, dual to open/closed string amplitudes in presence of D7-branes. We make use of supersymmetric localization techniques to evaluate the integrated correlators in terms of a matrix model, generating exact results in the gauge coupling. The results from QFT side in the ’t Hooft limit show some remarkable universality properties for the string/brane scattering processes.
