Chiral Bosonization of U_A(1)-currents and the Energy-Momentum Tensor in Quantum Chromodynamics

Abstract

Recently the new interest arised (hep-ph/0403139) to the chiral coefficients $L_{11},L_{12},L_{13}$ in the low-energy ChPT lagrangian describing the pseudoscalar meson coupling to gravity and/or light singlet dilatons. In 90ties we estimated these coefficients within the Chiral and Conformal Bosonization Model but published the results in the journal not easily accessible for the physics community. We put now our old paper to the E-archives.
