Description

Scattering amplitudes and multi-loop Feynman integral techniques play a central role in several areas of theoretical physics, including precision phenomenology for particle colliders and gravity. This workshop brings together researchers from particle physics and gravity to share their expertise. Its goal is to stimulate new ideas by combining different perspectives and approaches to the study of scattering amplitudes and Feynman integrals.

Program Overview: 

The program consists of 12 plenary talks followed by discussion sessions.
