Comments on gluon 6-point scattering amplitudes in N=4 SYM at strong coupling

Understand

We use the AdS/CFT prescription of Alday and Maldacena \cite{am} to analyze gluon 6-point scattering amplitudes at strong coupling in ${\cal N}=4$ SYM.

• By cutting and gluing we obtain AdS 6-point amplitudes that contain extra boundary conditions and come close to matching the field theory results.
• We interpret them as parts of the field theory amplitudes, containing only certain diagrams.
• We also analyze the collinear limits of 6- and 5-point amplitudes and discuss the results.
