    "abstract": "Motivated by the recent work on the calculation of the $\\pi NN$ coupling\nconstant using QCD sum rule beyond the chiral limit, we construct the\ncorresponding sum rules for the couplings, $\\eta NN$, $\\pi \\Xi\\Xi$, $\\eta\n\\Xi\\Xi$, $\\pi \\Sigma \\Sigma$ and $\\eta \\Sigma \\Sigma$. In constructing the\n$\\eta$-baryon sum rules, we use the second moment of the $\\eta$ wave function,\nwhich we obtain from the pion wave function after SU(3) rotation. In the SU(3)\nsymmetric limit, we can identify the term responsible for the $F/D$ ratio in\nthe OPE, which after the sum rule analysis gives $F/D\\sim 0.2$, a factor of 3\nsmaller than from other studies. We also present a qualitative analysis\nincluding the\n  SU(3) breaking terms.",
