In holographic CFT's, such as N=4 SYM, it is natural to organise the spectrum in single and multi particle states. By now we have a wealth of information about 4-point correlators with BPS single particle states, but much less is known about 4-point correlators involving multi particle states. I will discuss how we can calculate such correlators at strong coupling by using various techniques: bootstrap, OPE's of higher point functions and a bulk approach based on 1/2-BPS asymptotically AdS supergravity solutions. I will provide explicit results for various families of 4-point correlators with one or two 1/2-BPS multi particle states in the context of the AdS5/N=4 SYM duality.
