Abstract
We calculate the mass spectra of ${\mathrm{\ensuremath{\Lambda}}}_{c}$, ${\mathrm{\ensuremath{\Xi}}}_{c}$, ${\mathrm{\ensuremath{\Sigma}}}_{c}$, ${\mathrm{\ensuremath{\Xi}}}_{c}^{\ensuremath{'}}$, and ${\mathrm{\ensuremath{\Omega}}}_{c}$ baryons in the framework of a quark-diquark configuration using the relativistic flux tube model. The spin-dependent interactions are included in the j-j coupling scheme to find the complete mass spectra. We satisfactorily describe the known singly charmed baryons in a quark-diquark configuration. The possible spin-parity ${J}^{P}$ quantum numbers are assigned to several experimentally observed states. Furthermore, some useful mass predictions are given for more excited states that are reasonably consistent with other model predictions for lower excited states. From the obtained results, the Regge trajectories for these singly charmed baryons are constructed in the ($J$, ${M}^{2}$) plane, and the properties like linearity, parallelism, and equidistance are verified. Also, these predictions should be tested in future experiments.
