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