A quantum gluon is the gauge boson of the strong interaction. Gluons couple to color charge and mediate the interactions between quarks in quantum chromodynamics. Because gluons themselves carry color charge, they can interact with one another, giving QCD its distinctive confinement and jet behavior.[1][2][3]
Color field
Gluons are massless spin-1 bosons in the Standard Model. They are associated with the non-Abelian SU(3) color gauge symmetry of quantum chromodynamics. Unlike photons, gluons carry the charge to which they couple, so the strong field has self-interactions.[4]
Confinement and jets
At low energies, color confinement prevents isolated quarks and gluons from appearing as free particles. At high momentum transfer, asymptotic freedom makes perturbative calculations possible. Collider events reveal quarks and gluons indirectly as sprays of hadrons called jets.
Hadron structure
Gluons contribute substantially to the mass, spin structure, and internal dynamics of hadrons. They also dominate high-energy scattering processes and are essential for understanding quark-gluon plasma and early-universe strong-interaction matter.
