Pion-decay widths ofNandΔbaryons

Using a simple nonrelativistic quark model, we examine the decays of $p$-wave baryons to ground-state baryons via pion emission. As a consequence, the strength of the quark-quark-pion vertex can be estimated and is compared with the results of other authors. Further, investigation of relativistic corrections indicates that although the value of the $\mathrm{qq}\pi$ coupling can be highly dependent on the technique used for these corrections, it varies only moderately within a given technique for a range of energies of our interest.
