Using QCD sum rules, we compute the diagonal meson-baryon couplings, ฯ€NN, ฮทNN, ฯ€ , ฮท , ฯ€ and ฮท , from the baryon-baryon correlation function with a meson: i d 4 x e iqโ€ขx 0|T J B (x) JB (0) |M(p) . The calculations are performed to leading order in p ยต by considering the two separate Dirac structures
