Quantum chromodynamics - Wikipedia
In theoretical physics, quantum chromodynamics (QCD) is the study of the strong interaction between quarks mediated by gluons. Quarks are fundamental particles that make up composite 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).
Quantum chromodynamics (QCD) | Britannica
Quantum chromodynamics (QCD), in physics, the theory that describes the action of the strong force. QCD was constructed in analogy to quantum electrodynamics (QED), the quantum field theory of the electromagnetic force.
Quantum Chromodynamics (QCD) is the theory of strong interactions. It is formulated in terms of elementary fields (quarks and gluons), whose interactions obey the principles of a relativistic QFT, with a non-abelian gauge invariance SU(3).

Quantum Chromo Dynamics (QCD) (Foundations) • QCD is the theory of strong interaction of quarks, which is based on SU(3) c color symmetry. • It assumes each flavor of quark comes in three different colors. • The color states of quarks are SU(3) triplets. The color states of quarks are SU(3) c triplets.

quantum chromodynamics (QCD), Theory that describes the action of the strong force. The strong force acts only on certain particles, principally quark s that are bound together in the protons and neutrons of the atomic nucleus, as well as in less stable, more exotic forms of matter.
