| contents | The flavor-changing neutral current decays of heavy bottom quark, alongside the flavor-changing charged current processes mediated by $b \to (c, u)$ in semileptonic $B$ decays are emerged as powerful tools for exploring physics beyond the Standard Model. In this work, we focus on the feasibility of interpreting the processes mediated by $b \to c τν$ transitions, in particular, the semileptonic $b$-baryonic decay modes $Σ_b \to Σ_c^{(*)} τ^-\barν_τ$ and $Ξ_b \to Ξ_c τ^-\barν_τ$ in the context of SMEFT approach. We perform a detailed analysis of the sensitivity of new physics operators on various observables such as branching ratio, forward-backward asymmetry parameter, lepton non-universal observable and the longitudinal polarization fraction of the $b$-baryonic decay channels. |
