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.
