Asymptotic freedom
Asymptotic freedom is the property of the strong interaction that quarks interact more weakly at shorter distances, discovered in 1973 and honored with the 2004 Nobel Prize in Physics.
Gluon
The gluon is the spin-1 gauge boson of the strong interaction, which binds quarks into protons and neutrons; it was discovered at the PETRA collider in 1979.
Gluon field
The gluon field, also called the gluon four potential, is the gauge field of quantum chromodynamics, the SU(3) theory of the strong interaction, whose quanta are the gluons.
Strong interaction
The strong interaction, or strong nuclear force, is the fundamental force that binds quarks into protons and neutrons and, residually, holds atomic nuclei together; it is described by quantum chromodynamics.
