Quark-Gluon Plasma

Quark-gluon plasma is a state of dense matter with the quarks and gluons being its constituents. Soon after the Big Bang the matter was just in such a phase. When the Universe was expanding and cooling down the quark-gluon plasma turned into hadrons (neutrons and protons), which further formed the …

Physicists Find Quark

Physicists Find Strong Evidence of Four-Top Quark Production Physicists from the ATLAS Collaboration CERN’s Large Hadron Collider have uncovered strong evidence of the production of four top quarks. This rare process is expected to occur only once for every 70,000 pairs of top quarks created at the Large Hadron Collider. …
