CMS observes collective motion of particles in light-ion collisions, providing robust evidence of how initial nuclear geometry maps to final-state flow. For the first time, the CMS experiment has measured how particles flow in collisions of ox…

  The CMS experiment has analyzed the first-ever neon-neon collisions, looking for signs of quark-gluon plasma. By comparing these results with data from oxygen-oxygen, xenon-xenon, and lead-lead collisions, physicists find an interesting patter…

  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. When heavy ions such as l…
