Magnetic moments of the low-lying {1/2}^- octet baryon resonances

Abstract

The magnetic moments of the negative parity octet resonances with spin {1/2}: $N^{\ast }$(1535), $N^{\ast }$(1650), ${\Sigma }^{\ast }$(1620), and ${\Xi }^{\ast }$(1690) have been calculated within the framework of the chiral constituent quark model. In this approach, the presence of the polarized $q\bar{q}$ pairs (or the meson cloud, in other words) is considered by using the Lagrangian for Goldstone boson emission from the constituent quarks. Further, the explicit contributions coming from the spin and orbital angular momentum, including the effects of the configurations mixing between the states with different spins, are obtained. The motivation for these calculations comes from the recent interest in experimental measurement of the magnetic moment of the $S_{11}(1535)$ resonance and of similar calculations being done within lattice quantum chromodynamics approaches. Our results can be compared with those expected to come from these sources.
