Abstract |
In this work, the potential parameters of the independent quark model are systematically reduced using previously determined inputs from a broad range of baryons. The reduced-parameter formulation, developed within the relativistic Dirac formalism and employing a Martin-like potential, is then applied to the spectroscopy of the singly heavy baryons Xi c0 and Xi b- in anti-triplet(3 & strns;) and sextet(6) representations. This enables an explicit verification of the linear relation obtained between the potential parameters. Radially and orbitally excited state masses are calculated accordingly, and the resulting Regge trajectories are used to assign spin-parity of experimentally observed states. The observed states Xi c0(2882), Xi c0(2923), and Xi c0(2970) are interpreted as JP=32- states, where Xi c0(2882) is assigned to the anti-triplet (3 & strns;) configuration, while Xi c0(2923) and Xi c0(2970) are identified as sextet (6) states. In the bottom sector, the Xi b-(6227) state is interpreted either as a 3 & strns; baryon with JP=52+ or as a 6 baryon with JP=32+. To investigate the electromagnetic structure of these baryons, their magnetic moments and radiative decay widths are computed. Additionally, the two-body weak decay branching ratios of Xi c0 are evaluated and compared with experimental data to assess the robustness of the approach. The two-body nonleptonic decays of Xi b '- are also analyzed, providing predictions for branching ratios that may be tested in future experiments. Overall, the results demonstrate the effectiveness of the parameter-reduction procedure and support its applicability in the spectroscopy of heavy flavor baryons. |
