Abstract: I will present a method to compute four-point correlation functions with multiparticle operators in holography by using microstate geometries. Focussing on the simplest correlators, with two single and two double particles insertions, I will present explicit results for N=4 SYM. The key point of the method is to use precision holography to build a coherent operator made by a superposition of the multi-particle operators of interest, such that it interpolates between a geometry and a light particle. Then, a two-point Witten diagram in this background computes the generating function of the multiparticle correlators of interest. The problem in holography is mapped to a connection problem for the Heun equation, and the resulting correlator can be expressed as a generalized BMN integral. Finally, the resulting correlator can be tested against OPE predictions in the CFT, providing new and non-trivial checks of the AdS/CFT correspondence.
