Abstract
We calculate the hadronic coupling constants g(NN pi) and g(p pi pi) in QCD, including dynamical quarks in the framework of staggered fermions in the lattice approach. For the nucleon-pion coupling we obtain g(NN pi) = 13.8 +/- 5.8, to be compared with the experimental value 13.13 +/- 0.07 [1]. The rho pi pi coupling has been analysed for two different sets of operators with the averaged result g(p pi pi) = 4.2 +/- 1.9 which is to be compared with the experimental value 6.06 +/- 0.01 [2].
