The strong interaction as a research area encompasses theoretical and experimental studies of the fundamental force described by quantum chromodynamics (QCD), which governs the dynamics of quarks and gluons and the structure of hadrons and nuclei. It includes investigations of color confinement, asymptotic freedom, chiral symmetry breaking, and the phase structure of strongly interacting matter, such as the quark–gluon plasma. Methodologically, it spans perturbative QCD at high energies, lattice QCD and effective field theories at low energies, and phenomenology in high-energy collider, fixed-target, and heavy-ion experiments to test and refine the Standard Model’s strong sector.
