1. QCD - Noun
2. QCD - Proper 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 together

All quarks and gluons in QCD interact with each other through the strong force. Source: Internet
Definition Quantum electrodynamics (QED) has one electron field and one photon field; quantum chromodynamics (QCD) has one field for each type of quark ; and, in condensed matter, there is an atomic displacement field that gives rise to phonon particles. Source: Internet
A large body of experimental evidence for QCD has been gathered over the years. Source: Internet
Behaviour of the strong force The strong force is described by quantum chromodynamics (QCD), a part of the standard model of particle physics. Source: Internet
Flavor SU(3) is an approximate symmetry of the vacuum of QCD, and is not a fundamental symmetry at all. Source: Internet
