Properties of light flavour baryons in hypercentral quark model

Abstract

The light flavour baryons are studied within the quark model using the hypercentral description of the three-body system. The confinement potential is assumed as hypercentral Coulomb plus power potential (hCPP ν ) with power index ν. The masses and magnetic moments of light flavour baryons are computed for different power indices, ν, starting from 0.5 to 1.5. The predicted masses and magnetic moments are found to attain a saturated value with respect to variation in ν beyond the power index ν > 1.0. Further, we computed transition magnetic moments and radiative decay width of light flavour baryons. The results are in good agreement with the known experimental as well as other theoretical models.
