N+ρdecay of baryons in a flux-tube-breaking mechanism

A flux-tube-breaking mechanism motivated by QCD is extended to the analysis of the decay of nonstrange resonances into $N+\rho$. A proper threshold behavior is obtained by taking into account the instability of the $\rho$ meson. The only parameter of the model has previously been fixed to adjust the decay of $\Delta$ into $N+\pi$. We find a good agreement with the few available data and make predictions for many other resonances where data are needed.
