Hyperfine interactions in the D35, G37 and G39 sectors of the N=3 baryon spectrum

Abstract

Investigates the masses and compositions of the non-strange baryon resonances occurring in the D35, G37 and G39 sectors of the N=3 spectrum within the framework of the Isgur-Karl model, with due inclusion of hyperfine effects. Without performing a full fit to the N=3 baryon spectrum, the authors recover the pertinent features of a recent preliminary phase-shift analysis.
