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 Nw and ATT partial decay widths, assuming the pion emission takes place via a one-quark de-excitation. The agreement with experiment is very good.
We suggest that all configuration mixing within the 3 1-multiplet of SU(6) X O(3) is governed by simple decoupling conditions. We deduce a tentative set of ideal mixing angles and discuss the kind of models that might lead to such mixing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
