摘要：

We report on calculations of the hadronic coupling constants g(rhopipi) and g(NNpi) based on lattice QCD with four flavors of dynamical staggered fermions. By computing 2-point and 3-point Green's functions we have been able to determine these coupling constants ab initio from QCD; the results g(rhopipi) = 4.2 +/- 1.8 and g(NNpi) = 14.8 +/- 6 are compatible with the experimental values.
