The flavor changing decays of heavy bottom quarks to the correspondinglighter quarks ($u$, $c$ and $s$) in various $B$-meson decays via chargedcurrent and neutral current semileptonic transitions have emerged as promisingcandidates to explore the physics beyond the standard model. Experimentally thelepton flavor universality violation in $b \to (c,u)\,l\,\nu$ and $b \to s\,l^+l^-$ transitions have been reported to a higher precision. The measurements ofthe lepton flavor violating ratios such as $R_{D^{(*)}}$, $R_{J/\Psi}$ and$R_{K^{(*)}}$ are observed to deviate from the standard model expectations atthe level of $1.4\sigma$, $2.5\sigma$, $1.5\sigma$, $2.4\sigma$ and $2.2\sigma$respectively. Motivated by these anomalies, we investigate the lepton flavoruniversality violation in $\Sigma_b \to \Sigma_c l \nu$ and $\Omega_b \to\Omega_c l \nu$ decays. We follow a model independent effective field theoryformalism and study the implications of $R_{D^{(*)}}$ anomalies on $\Sigma_b\to \Sigma_c \tau \nu$ and $\Omega_b \to \Omega_c \tau \nu$ decay modes. Wegive predictions of various physical observables such as the ratio of branchingratios, total differential decay rate, forward-backward asymmetry, lepton sidepolarization fraction and convexity parameter within the standard model andwithin various new physics scenarios.
