ϒ mesons in light-ion collisions
The CMS experiment presents the first measurement of ϒ mesons – bound states of a bottom quark-antiquark pair – in oxygen-oxygen and neon-neon collisions, and strongly indicates that their production is suppressed owing to quark-gluon plasma droplets formed in such light-ion collisions.

Collective motion in tiny systems: oxygen and neon collisions as a window into nuclear structure
CMS observes collective motion of particles in light-ion collisions, providing robust evidence of how initial nuclear geometry maps to final-state flow.

LHC’s first oxygen-oxygen and neon-neon collisions – CMS spots an interesting pattern
The CMS experiment has analyzed the first-ever neon-neon collisions, looking for signs of quark-gluon plasma.

LHC’s first oxygen collisions – CMS spots signs of small-scale quark-gluon plasma
CMS scientists study the first-ever oxygen-oxygen collisions at the LHC, and observe signs of quarks and gluons losing energy when they travel through quark-gluon plasma – a state that existed just after the Big Bang.

First ever oxygen and neon LHC collisions are studied by CMS
This year, the LHC is colliding more than protons and lead ions: oxygen and neon have also made it into the collider, and are being studied by CMS and the other LHC experiments in order to understand the early universe!
