The tree-level $b\rightarrow c{\ell}\bar\nu_{\ell}$ based hadronictransitions have been on the focus of much attention since recordingsignificant deviations of the experimental data, on the ratios of the branchingfractions in $ \tau $ and $ e-\mu $ channels of the semileptonic $ B\rightarrow D $ transition, from the SM predictions by BaBar Collaboration in2012. It can be of great importance to look whether similar discrepancies takeplace in the semileptonic baryonic $\Lambda_{b}\rightarrow\Lambda_{c}{\ell}\bar\nu_{\ell}$ decay channel or not. In this accordance weestimate the decay width as well as the ratios of the branching fractions in $\tau $ and $ e-\mu $ channels of this baryonic transition by calculating theform factors, entering the amplitude of this transition as the main inputs, inthe framework of QCD sum rules in full theory. We compare the obtained resultswith the predictions of other theoretical studies. Our results may be comparedwith the corresponding future experimental data to look for possible deviationsof data from the SM predictions.
