Probing the R-parity violating supersymmetric effects in $B_c\to J/\psi {\ell }^{-}{\bar{\nu }}_{\ell },{\eta }_c{\ell }^{-}{\bar{\nu }}_{\ell }$ and ${\Lambda }_b\to {\Lambda }_c{\ell }^{-}{\bar{\nu }}_{\ell }$ decays

Motivated by recent $R_D$, $R_{D^{\ast }}$ and $R_{J/\psi }$ anomalies in $B\to D{\ell }^{-}{\bar{\nu }}_{\ell }$, $B\to D^{\ast }{\ell }^{-}{\bar{\nu }}_{\ell }$ and $B_c\to J/\psi {\ell }^{-}{\bar{\nu }}_{\ell }$ decays, respectively,…
