Decays of $N^*$ and $\Delta^*$ resonances into $N\rho$, $\Delta\pi$, and $N\sigma$

Abstract

The decays of $N^*$ and $\Delta^*$ resonances into $N\rho$, $\Delta\pi$ and $N\sigma$ 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 $\Delta(1232)\pi$, $N\rho$, $N\sigma$ are reported.
