Abstract

The decays of excited nonstrange baryons into the final states Delta eta and Delta omega are examined in a relativized quark pair creation model. The wave functions and parameters of the model are fixed by previous calculations of N pi and N pi pi, etc., decays through various quasi-two-body channels including N eta and N omega. Our results show that the combination of thresholds just below the region of interest and the isospin selectivity of these channels should allow the confirmation of several weakly established Delta baryons and the discovery of new Delta baryons in pion and photoproduction of these final states.
