N + rho decay of baryons in a flux tube breaking mechanism

[en] A flux-tube-breaking mechanism motivated by QCD is extended to the analysis of the decay of non-strange resonances into N + rho. A proper threshold behaviour 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.
