WebINTRODUCTION. Well before the advent of quantum chromodynamics (QCD), the theory of the strong force, it was realized that the essential ingredients of the hadronic world at low energies are chiral symmetry and its spontaneous breaking (see e.g. References 1, 2).Mainly through lattice QCD simulations, it has become well established that chiral … WebDec 15, 2024 · This symmetry is larger than the \(SU(2)_L\times SU(2)_R\times U(1)_A\) chiral symmetry of the QCD Lagrangian, which it contains as a subgroup.
