Spectroscopy of light baryons: Δ resonances

Abstract

The spectroscopy of light and strange baryons had been an important aspect with still unknown resonances and intrinsic baryonic properties. This paper focuses on the [Formula: see text] baryons treating [Formula: see text] and [Formula: see text] quarks with different constituent masses. The theoretical framework for calculating the resonance masses is hypercentral Constituent Quark Model (hCQM) with confining potential of the linear form. To account for the spin–orbit splitting in the correct order, first- and second-order corrections of the order [Formula: see text] and [Formula: see text] have been incorporated to the potential and spin-dependent term, respectively. The results obtained have been compared with many varied approaches as well as experimental available states. In addition to mass spectra, Regge trajectories for (n, [Formula: see text]) and ([Formula: see text], [Formula: see text]) have been plotted. The magnetic moment as well as transition magnetic moment have been calculated using effective quark mass. The radiative decay width has been studied for [Formula: see text] and [Formula: see text] channels.
