Query: Chiral Lagrangian and chiral quark model from confinement in QCD   The effective chiral Lagrangian in both nonlocal form $L_{ECCL}$ and standard
local form $L_{ECL}$ are derived in QCD using the confining kernel, obtained in
the vacuum correlator formalism.
  As a result all coefficients of $L_{ECL}$ can be computed via $q\bar q$
Green's functions.
  In the $p^2$ order of $L_{ECL}$ one obtains GOR relations and quark decay
constants $f_a$ are calculated $a=1,...8$, while in the $p^4$ order the
coefficients $L_1, L_2, L_3,L_4, L_5, L_6$ are obtained in good agreement with
the values given by data. The chiral quark model is shown to be a simple
consequence of $L_{ECCL}$ with defined coefficients.
  It is demonstrated that $L_{ECCL}$ gives an extension of the limiting
low-energy Lagrangian $L_{ECL}$ to arbitrary momenta.
