Chiral bosonization ofUA (1)-currents and the energy-momentum tensor in quantum chromodynamics

A generalization of the chiral lagrangian is obtained by extended low-temperature bosonization of vector, axial vector, scalar, and pseudoscalar U(3) quark currents. Estimates for its structural constants are given in accordance with the developed AANN model of QCD-bosonization. Following the ideology of chiral perturbation theory, we transform the bosonized chiral Lagrangian into the phenomenological form. Relations of Zweig-rule type are established. This enables us to express the new structural constants in terms of the given constants. The correspondence between the predictions obtained by the low-temperature bosonozation method and available phenomenological estimates are discussed. Bibliography: 9 titles.
