The inversed amplitude method and heavy baryon chiral perturbation theory applied to pion-nucleon scattering

We report on our present work, where by means of the Inverse Amplitude Method we unitarize the elastic pion nucleon scattering amplitudes of Heavy Barion Chiral Perturbation Theory at O(q(3)). We reproduce the scattering up to the inelastic thresholds including the Delta(1232) resonance. The fitted...
