Spin-orbit splitting in theN-Δ spectra and the deformed baryon model

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The absence of appreciable spin-orbit splitting in the low-lying even and odd parity states of the nucleon and delta is puzzling in conventional quark models. A constitutent quark model, in which the quarks interact through gluon as well as pion exchange, and the baryon is allowed to deform in the excited states, may provide a solution to the problem.
