| contents | Light-ion collisions at the LHC bridge the gap between small proton-proton and large heavy-ion collision systems, providing a unique laboratory to study the onset of QCD collective phenomena. The first light-ion run at the LHC took place July~1--9, 2025, with proton-oxygen (pO), oxygen-oxygen (OO), and neon-neon (NeNe) collisions. Early experimental results provide strong evidence of quark-gluon plasma (QGP) formation in these small systems. I review the motivation for the light-ion collisions and the first experimental results, connecting perturbative QCD, hot QCD, and low-energy nuclear structure physics. |
