Harmonic Oscillator Model for Baryons

摘要

Attention is drawn to a possible band structure displayed by the known N* resonances. The observed spectrum is similar to that predicted by a paraquark harmonic oscillator shell model. Exact three-body Schrodinger wave functions are used to compute the N-pi and Delta-pi partial decay widths, assuming the pion emission takes place via a one-quark de-excitation. The agreement with experiment is very good. (Author)
