LHC Forward Physics June 2025 Workshop

2 Jun 2025, 09:00 → 3 Jun 2025, 18:20 Europe/Zurich

6/2-024 - BE Auditorium Meyrin (CERN)

Christophe Royon (The University of Kansas (US)), Jesse Liu (New York University), Karel Cerny (Palacky University (CZ)), Murilo Santana Rangel (Federal University of Rio de Janeiro (BR))

The 2-3 June 2025 two-day workshop of the LHC Physics Centre at CERN (LPCC) Forward Physics Working Group provides a forum at CERN for experimental collaborations and theorists to meet and exchange latest results across all topics of forward physics at the LHC. 

Forward physics is a diverse program at the LHC that requires innovative instrumentation and unique techniques to measure high-rapidity particles missed by standard central detectors. Special instrumentation ranges from near-beam spectrometers to zero degree calorimeters. Recent results have witnessed a remarkable breadth of advances underscoring the creativity of this community:

• definitive elastic scattering measurements, 
• nonperturbative dynamics of the strong force,
• forward proton and neutron scattering,
• photon fusion production,
• collider neutrino measurements,
• searches for prompt and long-lived particles beyond the Standard Model,
• synergies with cosmic-ray observatories.

These developments open future opportunities to develop in exciting new directions.

This series of inter-experiment workshops provides a regular exchange of latest LHC results, ideas and techniques between experimentalists and theorists, sharpening open questions to chart future developments. We are a vibrant international community drawn to the richness of forward physics, where newcomers and early-career researchers are especially welcome to showcase their science.
