摘要Some problems concerned with normalization of wave functions, which are obtained from the general method for the Lorentz-covariant Bethe-Salpeter equation of the Goldstone boson developed in our previous work, are discussed in connection with the axial Ward-Takahashi identity. Physical properties of the pion, including the pi0 --> gammagamma amplitude, are calculated in QCD-motivated models with the general method. Both the chiral limit and the effect of explicit chiral-symmetry breaking by the bare quark mass are considered. A quite good agreement with experimental data is obtained with these models.
