We discuss a general strategy to compute the coefficients of the QCD chiral La-grangian using lattice QCD with Wilson fermions. This procedure requires the introduction of a lattice chiral Lagrangian as an intermediate step in the calculation. The QCD chiral Lagrangian is then obtained by expanding the lattice effective theory in increasing powers of the lattice spacing and the external mo-menta. In order to investigate the consequences of the chiral symmetry breaking induced by the Wilson term… CONTINUE READING
