Description
In the AdS/CFT context, 1/2-BPS asymptotically AdS supergravity solutions
can be used to derive holographic 4-point correlators. Beside reproducing
known strong-coupling results for the 4-point correlators with single
particle states, this approach can be used to derive new 4-point
correlators with two single particle and two multiparticle states. I will
provide some explicit examples of these correlators with double-particle
states both in AdS3 and AdS5. The results can be written in terms of a
natural generalisation of the usual D-functions appearing in the 4-point
correlators with single particle states.
