Description

We report on calculations of the hadronic coupling constants gρππ and gNNπ 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 gρππ=4.2±1.8 and gNNπ=14.8 ± 6 are compatible with the experimental values.
