Semileptonic $Ω_{b}\rightarrow Ω_{c}{\ell}\barν_{\ell}$ transition in full QCD
We investigate the semileptonic decay of $Ω_b\toΩ_c~{\ell}\barν_{\ell}$ in three lepton channels. To this end, we use QCD sum rule method in three point framework to calculate the form factors defining the matrix elements of these transitions. Having calculated the form factors as building blocks, we calculate the decay widths and branching fractions of the exclusive decays in all lepton channels and compare the results with other theoretical predictions. The obtained results for branching r…
