Scattering Amplitudes @ Liverpool

Mar 26, 2025, 2:00 PM → Mar 28, 2025, 10:30 PM Europe/London

Department of Mathematical Sciences

William J. Torres Bobadilla

The workshop Scattering Amplitudes @ Liverpool will focus on exploring efficient numerical evaluation techniques for scattering amplitudes in Quantum Field Theory. This event aims to foster collaboration and interactive discussions among researchers working in the UK, with emphasis on advancing theoretical predictions for low-energy processes.

The program includes presentations on recent developments, interactive group sessions, and collaborative discussions to tackle shared challenges and explore new directions. This workshop offers the opportunity to connect with experts in the field, with a welcoming atmosphere of a limited number of participants. 

The workshop will start on Wednesday 26th during the afternoon and will finish on Friday 28th at noon.
Attendance of the workshop is by invitation.
