Energy correlators in four-dimensional gravity
Dmitry Chicherin, Gregory P. Korchemsky, Emery Sokatchev +1
We investigate energy correlators in four-dimensional gravitational theories, which provide a simple class of infrared-finite observables. We compute the one- and two-point energy…
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…
Neural S-matrix bootstrap II: solvable 4d amplitudes with particle production
Mehmet Asim Gumus, Damien Leflot, Piotr Tourkine +1
We study a model for nonperturbative unitarization of the four-point contact scalar amplitude in four dimensions. It is defined through an infinite sum of planar diagrams, construc…
Conformal collider bootstrap in SYM
Ross Dempsey, Robin Karlsson, Silviu S. Pufu +2
We use a combination of perturbation theory, holography, supersymmetric localization, integrability, and numerical conformal bootstrap methods to constrain the energy-energy correl…
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…
The S-matrix bootstrap with neural optimizers I: zero double discontinuity
Mehmet Asim Gumus, Damien Leflot, Piotr Tourkine +1
In this work, we develop machine learning techniques to study nonperturbative scattering amplitudes. We focus on the two-to-two scattering amplitude of identical scalar particles,…
