Chiral symmetry breaking and formulas of quark conversion for low-energy hadronic matrix elements
Description
By using the extended Nambu-Jona-Lasinio model for the low-energy approximation of QCD the author derive the formulas, being due to spontaneous breaking of chiral symmetry and bosonization, and allowing to express matrix elements of any operator with current-quark fields in the definition in terms of matrix elements of this operator determined via constituent-quark fields interacting with low-lying meson states appearing as qq-collective excitations, which have the self-interactions too
