Spectral patterns in the nonstrange baryon spectrum

Abstract

We extract, from a quark model potential that reproduces the number and ordering of nonstrange baryonic resonances up to 2.3 GeV, the quantum numbers for the dominant configurations in the ground and first non-radial excited states. From the pattern of quantum numbers we identify, from data, spectral regularities that allow us to predict the expected high spin low-lying spectrum from 2.3 to 3.0 GeV. $N-\Delta$ degeneracies and $N$ parity doublets showing up can be interpreted in terms of a simple dynamics.
