摘要：
The method of QCD sum rules is used to analyze pion-baryon and kaon-baryon coupling constants. The procedure is based on the meson-to-vacuum matrix element of the corresponding two-point correlation function. All terms up to those of dimension 5 are retained in the operator-product expansion. The values obtained for the coupling constants are in reasonable agreement with experimental data. The sources of uncertainties are analyzed.
