Scientific definitions for quantum chromodynamics

quantum chromodynamics

A quantum field theory of the strong force that explains the interaction between particles with color charge, such as quarks and gluons. In quantum chromodynamics, particles interact through the strong force by exchanging gluons, which are the carriers of the strong force (much as photons are the carriers of the electromagnetic force in quantum electrodynamics). The theory is particularly important in theories of the atomic nucleus, whose nucleons are composed of quarks.
