Strong decays of qqq baryons

Abstract

We study strong decays of nonstrange baryons by making use of the algebraic approach to hadron structure. Within this framework we derive closed expressions for decay widths in an elementary-meson emission model and use these to analyze the experimental data for N* -> N + pi, N* -> Delta + pi, N* -> N + eta, Delta* -> N + pi, Delta* -> Delta + pi and Delta* -> Delta + eta decays.

Revised manuscript, 27 pages Revtex, 11 tables and 4 figures, to be published in Phys. Rev. D, February 1997
