Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.
A similar mysterious situation was with the Δ ++ baryon; in the quark model, it is composed of three up quarks with parallel spins. In 1964–65, Greenberg [19] and Han–Nambu [20] independently resolved the problem by proposing that quarks possess an additional SU(3) gauge degree of freedom, later called color charge.
The strength of the color force makes the properties of quark matter unlike gas or plasma, instead leading to a state of matter more reminiscent of a liquid. At high densities, quark matter is a Fermi liquid , but is predicted to exhibit color superconductivity at high densities and temperatures below 10 12 K.
Quantum chromodynamics is the study of the SU(3) Yang–Mills theory of color-charged fermions (the quarks) and gluons. Subcategories This category has the following 5 subcategories, out of 5 total.
Unlike the photon in electromagnetism, which is neutral, the gluon carries a color charge. Quarks and gluons are the only fundamental particles that carry non-vanishing color charge, and hence they participate in strong interactions only with each other. The strong force is the expression of the gluon interaction with other quark and gluon ...
According to quantum chromodynamics (QCD), quarks possess a property called color charge. There are three types of color charge, arbitrarily labeled blue, green, and red. [nb 6] Each of them is complemented by an anticolor – antiblue, antigreen, and antired. Every quark carries a color, while every antiquark carries an anticolor. [76]
Various charge quantum numbers have been introduced by theories of particle physics. These include the charges of the Standard Model: The color charge of quarks. The color charge generates the SU(3) color symmetry of quantum chromodynamics. The weak isospin quantum numbers of the electroweak interaction.
In a QGP, the color charge of the quarks and gluons is screened. The QGP has other analogies with a normal plasma. There are also dissimilarities because the color charge is non-abelian, whereas the electric charge is abelian. Outside a finite volume of QGP the color-electric field is not screened, so that a volume of QGP must still be color ...
