In theoretical physics, quantum chromodynamics (QCD) is the theory of strong interactions, a fundamental force describing the interactions between quarks and gluons which make up hadrons such as the proton, neutron and pion. QCD is a type of quantum field theory called a non-abelian gauge theory with symmetry group SU(3). The QCD analog of electri...

(QCD) A quantum field theory that describes the properties of the strong interactions between quarks and between protons and neutrons in the framework of quantum theory and the special theory of relativity. Quarks have a distinctive property called color which governs their bi...

QCD noun a theory of strong interactions between elementary particles (including the interaction that binds protons and neutrons in the nucleus); it assumes that strongly interacting particles (hadrons) are made of quarks and that gluons bind the quarks toge...

In physics, a theory describing the interactions of quarks, the elementary particles that make up all hadrons (subatomic particles such as protons and neutrons). In quantum chromodynamics, quarks are considered to interact by exchanging particles called gluons, which carry the strong nuclear force, and whose role is to `glue` quarks toget...

a quantum field theory that describes quarks and gluons and their interactions, with the color of the quarks playing a role analogous to that of electric charge. Abbr.: QCD Also calledCf.(def. 18).
