We are pleased to announce the 2025 edition of the Light Ion Collisions at the LHC workshop.

The workshop aims to bring the community together for celebrating and assessing the scientific reach of experimental results on light-ion collisions collected at the LHC in July 2025.

The goal is to clarify what we have learned from existing measurements and to define the most pressing open questions going forward. We will also hold a community discussion on the scientific potential of future light-ion runs in 2026 and beyond.

Workshop topics include:

• Experimental overviews of collectivity and energy loss
• Hydrodynamics and non-equilibrium dynamics
• Jet quenching in small systems
• nPDFs of light ions
• Synergies with nuclear structure physics and other areas
• Accelerator and experiments perspectives for future light-ion runs

Anyone interested in the workshop is invited to register.
