EMMI Workshop: Light-ion collisions 2026

We study charged-particle multiplicity distributions in OO, NeNe, XeXe, and PbPb collisions within the wounded-parton Glauber framework with overlayed negative binomial fluctuations, implemented in GLISSANDO. We fit directly the multiplicity distributions (histograms), simultaneously across all the systems, using the same model parameters for each reaction. The fit is performed in 1–80 %...

The recent light-ion runs at the LHC, specifically oxygen–oxygen (OO) and neon–neon (NeNe) collisions, have been remarkably successful, offering valuable new insights into Quark-Gluon Plasma (QGP) formation and collectivity in small systems. Despite this success, some tensions remain between the experimental measurements reported by different collaborations. A key potential source of these...

The 2025 light ion run has inspired exciting new experimental and theoretical work in the scientific communities at CERN and RHIC. The unique OO, NeNe and pO datasets collected in just over a week of beam time have triggered a wave of new analyses and studies aimed at deeper understanding of the strong nuclear force in both cold and hot regimes, spanning from the modification of cold oxygen...
