Pion decay of baryons in a flux-tube quark model

Pion decay widths of non-strange baryon resonances are calculated based on the 3P_0 quark-pair creation model. The decay mechanism is consistent with the description of the nucleon and of the pion as having quark structure related to a flux-tube model motivated by QCD. The spectroscopic model has no adjustable parameter. The 3P_0 has one parameter which we fit to reproduce the Delta(1232) decay width. The results for 19 resonances are compared to experiment and to results obtained from the pseudo-scalar emission model. This sheds some light on the role of the finite size of the pion.
