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…

BPS Wilson loops in mass-deformed ABJM theory: Fermi gas expansions and new defect CFT data
Elisabetta Armanini, Luca Griguolo, Luigi Guerrini
We compute the expectation values of BPS Wilson loops in the mass-deformed ABJM theory using the Fermi gas technique. We obtain explicit results in terms of Airy functions, effecti…
