Description
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.
