Quark–gluon plasma - Wikipedia
WEBQuark–gluon plasma (QGP or quark soup) is an interacting localized assembly of quarks and gluons at thermal (local kinetic) and (close to) chemical (abundance) equilibrium. The word plasma signals that free color charges are allowed.
Heavy ions and quark-gluon plasma - CERN
WEBThe degree of jet quenching – a figure that emerges in data from millions of collision events – plus the jets' orientation, directionality, composition, and how they transfer energy and momentum to the medium, reveal what’s inside the fireball and thus the properties of the quark-gluon plasma.
Explained: Quark-gluon plasma - MIT News
WEBJun 9, 2010 · Over the past decade, physicists around the world have been trying to re-create that soup, known as quark-gluon plasma (QGP), by slamming together nuclei of atoms with enough energy to produce trillion-degree temperatures.
DOE Explains...Quarks and Gluons | Department of Energy
WEBBecause of this, quarks and gluons are bound inside composite particles. The only way to separate these particles is to create a state of matter known as quark-gluon plasma. In this plasma, the density and temperature are so high that protons and neutrons melt.

WEBJul 18, 2007 · When temperatures or densities become very high, strongly interacting quarks and gluons become free and transform themselves into a new, deconfined phase of matter, for which the term...
A ten-year journey through the quark–gluon plasma and beyond
WEBNov 9, 2022 · These heavy-ion collisions recreate the quark–gluon plasma (QGP): the hottest and densest fluid ever studied in the laboratory. In contrast to normal nuclear matter, the QGP is a state where quarks and gluons are not confined inside hadrons.
ALICE explores the hidden charm of quark–gluon plasma
WEBOct 20, 2022 · A new analysis from the international ALICE collaboration at the LHC investigates how different bound states of a charm quark and its antimatter counterpart, also produced in these collisions, are affected by quark–gluon plasma.
CERN claims first experimental creation of quark–gluon plasma
