Özet

New relations between Borel QCD sum rules for the strong couplings of baryons to kaons are derived. It is shown that, on the basis of the sum rules for the coupling constants g(pi Sigma Sigma) and g(pi Sigma Lambda), the corresponding sum rules can be directly obtained for the coupling constants g(KYN) and g(KY Xi), Y = Sigma, Lambda. The values of these coupling constants are calculated in the fiducial interval 1.0 <= M-2 <= 1.4 GeV2 at t = -1.
