In this work, we study the properties of charm- and bottom-flavored baryons in the approximative quark-diquark modelin which the structure of baryons is considered as the bound states of quark-diquark pairs instead of the usual three equivalent quarks. To this aim, we use the Bethe-Salpeter equation including the Yukawa potential between the constituent quarks of baryons. Performing a fit procedure on the baryon masses in their ground state, we first determine the free parameters in the Yukawa potential and then compute the heavy baryons masses and energies in their excited states. We will also compute the magnetic moments of single heavy baryons as well as their semileptonic decay widths by evaluating the Isgur-Wise functions (IWF) for heavy baryons. Our results will be compared with available experimental data and other models so that the consistencies between them ensure the validity of IWF parameters extracted for the transitions of bottom baryons into charmed ones. Relying on the diquark model, we shall also predict the properties of some levels which have not yet observed.
