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 interaction ...

Collisions between protons and lead ions at the Large Hadron Collider (LHC) have produced surprising behavior in some of the particles created by the collisions. The new observation suggests the collisions ...
