CMS observes melting of Upsilon particles in heavy-ion collisions
In 2011, CMS presented early evidence that Upsilon (Υ) particles produced in lead-lead collisions “melt” as a consequence of interacting with the hot nuclear matter created in these heavy-ion interactions.

Important heavy-ion results from CMS
The CMS experiment has made several unique measurements using data from LHC collisions of lead nuclei (PbPb, November 2010) at centre-of-mass energies of 2.76 TeV per nucleon pair.

CMS observes hints of melting of Upsilon particles in lead-nuclei collisions
In our Universe today, quarks are always bound together by gluons to form “composite” particles such as protons and neutrons.

Jet Quenching observed by CMS in heavy-ion collisions
After only three weeks of heavy-ion running at CERN’s Large Hadron Collider (LHC), the CMS experiment is already yielding new insights into the condition of matter that existed in the very first instants of the Universe’s life, some 13.7 billion years ago.

First heavy-ion collisions in CMS
The CMS experiment at CERN’s Large Hadron Collider (LHC) has recorded its first Lead-Lead collisions at a centre-of-mass energy of 2.76 TeV per nucleon pair, marking the start of its heavy ion research programme.
