We analyze the One Boson Exchange Potential from the point of view ofRenormalization theory. We show that the nucleon-meson Lagrangean whilepredicting the NN force does not predict the NN scattering matrix nor thedeuteron properties unambiguously due to the appearance of short distancesingularities. While the problem has traditionally been circumvented byintroducing vertex functions via phenomenological strong form factors, wepropose to impose physical renormalization conditions on the scatteringamplitude at low energies. Working in the large Nc approximation withpi,sigma,rho and omega mesons, we show that, once these conditions are applied,results for low energy phases of proton-neutron scattering as well as deuteronproperties become largely insensitive to the form factors and to the vectormesons and yield a reasonable agreement with the data, for realistic values ofthe coupling constants.
