Abstract
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 πΣΣ and g πΣΛ, the corresponding sum rules can be directly obtained for the coupling constants g KYN and g KYΞ, Y = Σ,Λ. The values of these coupling constants are calculated in the fiducial interval 1.0 ≤ M 2 ≤ 1.4 GeV2 at t = −1.
