Comments on gluon 6-point scattering amplitudes in š’© = 4 SYM at strong coupling

Abstract: Abstract:We use the AdS-CFT prescription of Alday and Maldacena [1] to analyze gluon 6-point scattering amplitudes at strong coupling in 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.

“…Let us now return to the analysis of the cusp divergences of the light-like Wilson loops and take advantage of both the axial gauge and the exponentiation (20). A characteristic feature of the 'webs' following from their maximal non-Abelian nature is that the corresponding Feynman integrals have 'maximally complicated' momentum loop flow.…”
