These component parts are neutrons and protons, which are collectively called nucleons. Nuclear binding energy is the energy that would be required to disassemble the nucleus of an atom into its component parts. This strength is modified by the gauge color charge of the particle, a group theoretical property. The strength of interaction is parametrized by the strong coupling constant. All quarks and gluons in QCD interact with each other through the strong force. The strong force is the expression of the gluon interaction with other quark and gluon particles. 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. Mathematically, QCD is a non- Abelian gauge theory based on a local (gauge) symmetry group called SU(3). The strong force is described by quantum chromodynamics (QCD), a part of the standard model of particle physics. This property of the strong force is called color confinement, and it prevents the free "emission" of the strong force: instead, in practice, jets of massive particles are produced. Thus, if hadrons are struck by high- energy particles, they give rise to new hadrons instead of emitting freely moving radiation (gluons). The strong force inherently has such a high strength that hadrons bound by the strong force can produce new massive particles. In the latter context, it is often known as the color force. The strong interaction is observable at two ranges: on a larger scale (about 1 to 3 femtometers (fm)), it is the force that binds protons and neutrons (nucleons) together to form the nucleus of an atom. Most of the mass of a common proton or neutron is the result of the strong force field energy the individual quarks provide only about 1% of the mass of a proton. In addition, the strong force binds neutrons and protons to create atomic nuclei. The strong nuclear force holds most ordinary matter together because it confines quarks into hadron particles such as proton and neutron. In particle physics, the strong interaction is the mechanism responsible for the strong nuclear force (also called the strong force or nuclear strong force), and is one of the four known fundamental interactions, with the others being electromagnetism, the weak interaction and gravitation.
