Descripción
We perform a phenomenological analysis on the use of N(1232) alternative couplings in N scattering, within a single and well-controlled dynamical model. We compare numerical results for the elastic cross section obtained using the conventional couplings, already adopted in several reaction calculations, with those obtained with the so-called spin-3/2 gauge-invariant vertexes suggested recently. Confronting with experimental cross-sectional data in the region around the resonance, we see that these results are by no means equivalent and the differences between them cannot be eliminated by a readjustment of free parameters of the meson-exchange contributions. We find that the use of the conventional couplings leads to better fits. © 2012 IOP Publishing Ltd.
