Description
Summary: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 ( J P = 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.
