CERN announced today (see CERN announcement) that a relevant new effect has been observed by CMS experiment at LHC. Due to its deep similarities with the analogous effect seen at heavy ion collision facilities, it is possibly the first observation of a quark-gluon plasma in proton collisions in a high-energy experiment. A paper has been sent out for review. They made quark bound looser indeed. A first important finding from LHC.
