Explaining the {mathcal{R}}(D) and {mathcal{R}}(D^(ast)) Anomalies in the B-L Supersymmetric Standard Model with Inverse Seesaw

We investigate the ${\mathcal{R}}(D)$ and ${\mathcal{R}}(D^{\ast})$ anomalies in the context of the $B-L$ extension of the Minimal Supersymmetric Standard Model with Inverse Seesaw. We demonstrate that the lepton penguin $W^{\pm}l \bar\nu_l $ ($l=e,\mu,\tau$) mediated by CP-even/odd right-handed sneutrinos, charginos and neutralinos can account for these anomalies simultaneously.
