Description

We conduct an investigation on the spin $ \frac{3}{2}\to \frac{1}{2}$ semileptonic weak transition of single heavy baryons for the exclusive decay $ {\mathrm{\Sigma }}_{b}^{*0}\to {\mathrm{\Sigma }}_{c}^{+}\ell {\overline{\nu }}_{\ell }$ in three possible lepton channels within the three point QCD sum rule method. We compute the responsible form factors of this semileptonic decay by incorporating both perturbative and nonperturbative contributions of the operator product expansion series up to a mass dimension six. Having acquired the form factors, the decay widths of the processes in all lepton channels are determined. Our findings as well as possible future experimental information can be employed in order to check the SM predictions and explore the possibility of new physics in heavy baryonic decay channels.
