Description

I will discuss scattering amplitudes in strongly coupled N=4 super Yang-Mills theory in the multi-Regge limit. In the strong coupling regime, the calculation of the scattering amplitudes reduces to the solution of a system of non-linear, coupled integral equations through the AdS/CFT-correspondence. These equations reduce to standard Bethe ansatz equations in the multi-Regge limit. In this kinematical regime, scattering amplitudes in N=4 SYM are physically described by bound states of effective particles, the so-called Reggeons. The six- point remainder function is fully described by a two-Reggeon bound state and is known at finite coupling. At eight external gluons a three-Reggeon bound state starts to appear about which much less is known. We investigate the three-Reggeon bound state in the strong coupling regime and try to make some generalisations to multiple-Reggeon bound states.
