Masses and magnetic moments of triple heavy flavour baryons in hypercentral model

Triple heavy flavour baryons are studied using the hypercentral description of the three-body system. The confinement potential is assumed as hypercentral Coulomb plus power potential with power index p. The ground state (JP = ½+ and 3/2+) masses of heavy flavour baryons are computed for different power index, p starting from 0.5 to 2.0. The predicted masses are found to attain a saturated value with respect to variation in p beyond the power index p > 1.0. Using the spin-flavour structure of the constituting quarks and by defining effective mass of the confined quarks within the baryons, the magnetic moments are computed with no additional free parameters.

Properties of light flavour baryons in hypercentral quark model

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 (hCPPν) 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.

Single heavy flavour baryons using Coulomb plus a power law interquark potential

Properties of single heavy flavor baryons in a non-relativistic potential model with colour Coulomb plus a power law confinement potential have been studied using a simple variational method. The ground-state masses of single heavy baryons and the mass difference between the JP =

+ states are computed using a spin-dependent two-body potential. Using the spin-flavour structure of the constituting quarks and by defining an effective confined mass of the constituent quarks within the baryons, the magnetic moments are computed. The masses and magnetic moments of the single heavy baryons are found to be in accordance with the existing experimental values and with other theoretical predictions. It is found that an additional attractive interaction of the order of -200 MeV is required for the antisymmetric states of
