Using QCD sum rules, we compute the diagonal meson-baryon couplings, πNN, ηNN, π , η , π and η , from the baryon-baryon correlation function with a meson: i d 4 x e iq•x 0|T J B (x) JB (0) |M(p) . The calculations are performed to leading order in p µ by considering the two separate Dirac structures
