Coupling constants of the pseudoscalar mesons to the octet baryons are
computed in the QCD sum rule approach. The pi-NN, eta-NN, pi-XiXi, eta-XiXi,
pi-SigmaSigma, eta-SigmaSigma as well as pi-Lambda-Sigma couplings are studied.
Determining the pertinent Dirac structure in the correlation function, we
analyze the couplings in the SU(3) limit. We find the F/D ratio to be \sim
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.Comment: 4 pages, Talk given at XVI International Conference on Particles and
