Abstract

The decays of N^* and Δ^* resonances into Nρ, Δπ and Nσ final states are studied in a coupled-channel analysis of data on pion- and photo-induced reactions. Improvements in the fit were observed when new resonance contributions were introduced. Frequencies for the intermediate isobars Δ(1232)π, Nρ, Nσ are reported.
