Spin-Flavor van der Waals Forces and NN interaction

We study the Nucleon-Nucleon interaction in the Born-Oppenheimer approximation at second order in perturbation theory including the \Delta
resonance as an intermediate state. The potential resembles strongly chiral potentials computed either via soliton models or chiral perturbation theory and has a van der Waals like singularity at short distances which is handled by means of renormalization techniques. Results for the deuteron are discussed.
