Abstract

Using the general form of the baryon currents, we calculate the meson-baryon coupling constants and the F/D ratio within the framework of light cone QCD sum rules in the SU(3) flavor symmetry limit. The dependence of the results on the Dirac structure and on the free parameter b appearing in the general baryon current is considered. The comparison of our results on the F/D ratio with the existing results is presented.
