  The flavor changing decays of heavy bottom quarks to the corresponding
lighter quarks ($u$, $c$ and $s$) in various $B$-meson decays via charged
current and neutral current semileptonic transitions have emerged as promising
candidates to explore the physics beyond the standard model. Experimentally the
lepton 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 of
the lepton flavor violating ratios such as $R_{D^{(*)}}$, $R_{J/\Psi}$ and
$R_{K^{(*)}}$ are observed to deviate from the standard model expectations at
the 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 flavor
universality 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 theory
formalism 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. We
give predictions of various physical observables such as the ratio of branching
ratios, total differential decay rate, forward-backward asymmetry, lepton side
polarization fraction and convexity parameter within the standard model and
within various new physics scenarios.
