Qu'est-ce (qui) est quark gluon plasma - définition

PRINCIPLE PREVENTING HADRONS (QUARKS BOUND BY THE STRONG FORCE USING GLUONS) FROM BEING SEPARATED INTO FREE INDIVIDUAL QUARKS
Quark confinement; QCD string; Infrared slavery; Quark Confinement; Quark de-confinement; Quark deconfinement; Colour confinement; Gluon tube; Confinement (physics)
  • An animation of color confinement. If energy is supplied to the quarks as shown, the gluon tube elongates until it reaches a point where it "snaps" and forms a quark–antiquark pair. Thus single quarks are never seen in isolation.

PHASE OF QUANTUM CHROMODYNAMICS CHARACTERISED BY AN ASSEMBLY OF QUARKS AND GLUONS AT THERMAL AND CHEMICAL EQUILIBRIUM
Deconfining phase; Quark gluon plasma; Qgp; Quark soup; QGP; Quark Gluon Plasma; Quark-gluon plasma; Quark−gluon plasma; Quark plasma; Glasma; Quark-Gluon Plasma; RHIC fireball
Quarkgluon plasma (QGP) 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.

These results demonstrate that all these particles are produced in explosively hadronizing fireball (of QGP) and do not undergo further interaction once produced. This key result shows therefore formation a new state of matter announced at CERN in February 2000.
SUBATOMIC SIGNATURE
Strangeness production; Strangeness enhancement; Strangeness in relativistic heavy ion collisions; Strangeness and quark-gluon plasma
In high-energy nuclear physics, strangeness production in relativistic heavy-ion collisions is a signature and diagnostic tool of quarkgluon plasma (QGP) formation and properties. Unlike up and down quarks, from which everyday matter is made, heavier quark flavors such as strangeness and charm typically approach chemical equilibrium in a dynamic evolution process.

  • Avalanche effect between two electrodes. The original ionization event liberates one electron, and each subsequent collision liberates a further electron, so two electrons emerge from each collision: the ionizing electron and the liberated electron.

Gas so rarefied that its molecules do not collide, or rarely do so; radiant matter, q. v. [Transcriber's note: This term now refers to plasma, an ionized gas, which contains free electrons. The ions and electrons move somewhat independently making plasma electrically conductive. It responds strongly to electromagnetic fields.]

Color confinement

In quantum chromodynamics (QCD), color confinement, often simply called confinement, is the phenomenon that color-charged particles (such as quarks and gluons) cannot be isolated, and therefore cannot be directly observed in normal conditions below the Hagedorn temperature of approximately 2 terakelvin (corresponding to energies of approximately 130–140 MeV per particle). Quarks and gluons must clump together to form hadrons. The two main types of hadron are the mesons (one quark, one antiquark) and the baryons (three quarks). In addition, colorless glueballs formed only of gluons are also consistent with confinement, though difficult to identify experimentally. Quarks and gluons cannot be separated from their parent hadron without producing new hadrons.
