Partial DecayWidths of Negative Parity Baryons in the 1/N_c Expansion

摘要

The partial decay widths of lowest lying negative parity baryons belonging to the 70- plet of SU(6) are analyzed in the framework of the 1/N_c expansion. The channels considered are those with single pseudoscalar meson emission. The analysis is carried out to sub-leading order in 1/N_c and to first order in SU(3) symmetry breaking. Conclusions about the magnitude of SU(3) breaking effects along with predictions for some unknown or poorly determined partial decay widths of known resonances are given.
