Radial Excited States of the Nucleon in Quark Models with Dynamical Confinement

Abstract

The P11(1440) (Roper) resonance 1 is the lowest positive-parity N state, most clearly visible in partial-wave decompositions of πN → πN and πN → ππN scattering, as well as in pion photoproduction. Although this four-star resonance is within the energy reach of many modern research facilities, the experimental analyses so far have not ventured beyond the… (More)
