Physics:Quantum gluon field
The quantum gluon field is the gauge field of quantum chromodynamics. Its excitations are gluons, which mediate the strong interaction between quarks and other color-charged particles. Because gluons themselves carry color charge, the gluon field has strong self-interactions that lead to confinement, jets, and the complex internal structure of hadrons.[1][2]
Color gauge field
The gluon field is associated with the non-Abelian SU(3) color symmetry of quantum chromodynamics. It couples to color charge and has several field components corresponding to the generators of the color symmetry.[3]
Self-interaction and confinement
Unlike photons, gluons interact with one another. This self-coupling is responsible for many distinctive strong-interaction effects, including asymptotic freedom at short distances and confinement at long distances.[4]
Hadron physics
Inside protons, neutrons, mesons, and other hadrons, gluon fields contribute substantially to mass, momentum, spin structure, and binding. Collider experiments observe gluon dynamics indirectly through jets and hadron production.[5]
