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 SYM as functions of the Coulomb-branch parameters and kinem…

From Partons to Strings: Scattering on the Coulomb Branch of SYM
Luis F. Alday, Elisabetta Armanini, Kelian Häring +1
We study scattering on the Coulomb branch of planar SYM at finite 't Hooft coupling. This setup defines a family of classical open-string S-matrices that smoothly…

What is the graviton pole made of?
Kelian Häring, Alexander Zhiboedov
We explore the physical mechanisms responsible for generating the graviton pole in twice-subtracted dispersion relations, both in flat space and in AdS. To characterize these mecha…
