The symposium will take place at ETH Zurich from 17th to 19th November 2025, and will focus on recent developments and open challenges in applying foundational QCD principles to precision collider physics and hadronic phenomena.
A one-day workshop on Numerical Perturbative QFT will be held on November 20th, 2025 (the day after the end of the symposium), featuring presentations of numerical applications of many of the methods discussed during the symposium.
All symposium participants are welcome to attend this follow-up event as well.
Discussions will center on factorization formalisms and infrared-safe observables, which remain critical for connecting perturbative predictions to experimental measurements.
Topics include:
- Factorization theorems and collider phenomenology.
- Resummation, parton showers and matching.
- Glauber regions and factorization.
- Power corrections.
- Local infrared subtraction methods.
- Recent advances in perturbative methods.
In conjunction with this event, we will also celebrate the 40th anniversary of the landmark paper by John Collins, Dave Soper, and George Sterman on factorization for short-distance hadron-hadron processes. One of the highlights of the symposium will be a panel discussion on the role of factorization in quantum field theory and collider physics.
