      More Details Abstract Fulltext PDF

      Heavy flavor baryons containing single and double charm (beauty) quarks with light flavor combinations are studied using the hypercentral description of the three-body problem. The confinement potential is assumed as hypercentral Coulomb plus power potential with power index 𝜈. The ground state masses of the heavy flavor, $J^{P} = \dfrac{1}{2}^{+}$ and $\dfrac{3}{2}^{+}$ baryons are computed for different power indices, 𝜈 starting from 0.5 to 2.0. The predicted masses are found to attain a saturated value in each case of quark combinations beyond the power index $\nu = 1.0$.

      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 ($J^{P} = \dfrac{1}{2}^{+}$ and $\dfrac{3}{2}^{+}$) 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.

      More Details Abstract Fulltext PDF

      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$_\nu$ ) 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 $\nu > 1.0$. 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.
