Decays of $N^{\ast }$ and ${\Delta }^{\ast }$ resonances into $N\rho$, $\Delta \pi$, and $N\sigma$

Abstract

The decays of $N^{\ast }$ and ${\Delta }^{\ast }$ 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.
