Abstract
Coupling constants of the pseudoscalar mesons to the octet baryons are computed in the QCD sum rule approach. The πNN, ηNN, πξξ, ηξξ, πΣΣ, ηΣΣ as well as πΓΣ coulings are studied. Determining the pertinent. Diract structure in the correlation function, we analyze the couplings in the SU(3) limit. We find the F/D ratio to be ∼0.6 − 0.8 that is consistent with the SU(6) value. We also estimate the SU(3) breaking effect using a projected correlation function method.
