Walking Sudakov: From Cusp to Octagon

Luis F. Alday, Elisabetta Armanini, Andrei V. Belitsky +2

We study the Sudakov form factor and the four-point scattering amplitude on the Coulomb branch of planar $N = 4$ SYM as functions of the Coulomb-branch parameters and kinem…

From Partons to Strings: Scattering on the Coulomb Branch of $N = 4$ SYM

Luis F. Alday, Elisabetta Armanini, Kelian HÃ¤ring +1

We study scattering on the Coulomb branch of planar $N = 4$ SYM at finite 't Hooft coupling. This setup defines a family of classical open-string S-matrices that smoothly…
