Title: Quasi-two-body decays of nonstrange baryons

Quasi-two-body decays of nonstrange baryons We examine the decays of nonstrange baryons to the final states [Delta][pi], [ital N][rho], [ital N][eta], [ital N][eta][prime], [ital N][omega], [ital N]1/2[sup +](1440)[pi], and [Delta]3/2[sup +](1600)[pi], in a relativized pair-creation ([sup 3][ital P][sub 0]) model which has been developed in a previous study of the [ital N][pi] decays of the same baryon states. As it is our goal to provide a guide for the possible discovery of new baryon states at CEBAF and elsewhere, we examine the decays of resonances which have already been seen in the partial-wave analyses, along with those of states which are predicted by the quark model but which remain undiscovered. The level of agreement between our calculation and the available widths from the partial-wave analyses is encouraging.
