Comments on gluon scattering amplitudes via AdS/CFT

Understand

In this article we consider n gluon color ordered, planar amplitudes in N=4 super Yang Mills at strong 't Hooft coupling.

• These amplitudes are approximated by classical surfaces in AdS_5 space.
• We compute the value of the amplitude for a particular kinematic configuration for a large number of gluons and find that the result disagrees with a recent guess for the exact value of the amplitude.
• Our results are still compatible with a possible relation between amplitudes and Wilson loops.
