Strong interaction

The strong interaction or strong force is today understood to represent the interactions between quarks and gluons as detailed by the theory of quantum chromodynamics. The strong force is the fundamental force mediated by gluons, acting upon quarks, antiquarks, and the gluons themselves.

Although the strong force only acts upon elementary particles directly, the force is only observed interacting with hadrons as the nuclear force. As has been shown by many failed free quark searches, the elementary particles affected are unobservable directly. This phenomenon is called confinement, a theory which allows only hadrons to be seen.
