ATLAS explores the quark–gluon plasma with light-ion collisions
ATLAS explores the quark–gluon plasma with light-ion collisions In July 2025, ATLAS recorded the first-ever collisions of light ions at the LHC — oxygen–oxygen (O–O) and neon–neon (Ne–Ne) — marking a new phase in the study of strongly interacting matter. These short, intense runs provided a unique opportunity to explore the transition between conventional hadronic

LHCb explores new physics in special light-ion LHC runs
LHCb explores new physics in special light-ion LHC runs The LHC carried out a special run programme early summer. First results were reported by the ALICE, ATLAS, CMS and LHCb experiments at the Initial Stages of High-Energy Nuclear Collisions conference. These results were also presented at a CERN seminar and reported in a CERN news.

CMS explores light-ion collisions: suppression, scaling, and collectivity
CMS explores light-ion collisions: suppression, scaling, and collectivity The CMS experiment has reported first results from the LHC’s dedicated oxygen–oxygen (O–O) and neon–neon (Ne–Ne) collision run, offering an unprecedented look at quark–gluon plasma (QGP) formation in light-ion systems. These studies address long-standing questions about the minimal conditions required for QGP droplets to form and how

ALICE explores the quark–gluon plasma with light-ion collisions
ALICE explores the quark–gluon plasma with light-ion collisions In July 2025, the ALICE experiment took part in the LHC’s first-ever light-ion campaign, colliding oxygen–oxygen (O–O) and neon–neon (Ne–Ne) nuclei at a centre-of-mass energy of 5.36 TeV per nucleon pair. The short but intense runs offered a rare opportunity to explore the transition between ordinary hadronic
