  <dc:description>We investigate     ${R}_{D}$   and     ${R}_{{D}^{\ast }}$   anomalies in a low scale left–right symmetric model based on     $SU{\left(3\right)}_{C}×SU{\left(2\right)}_{L}×SU{\left(2\right)}_{R}×U{\left(1\right)}_{B-L}$   with a simplified Higgs sector consisting of only one bidoublet and one     $SU{\left(2\right)}_{R}$   doublet. The Wilson coefficients relevant to the transition     $b\to c\tau \nu $   are derived by integrating out the charged Higgs     ${H}^{±}$   boson, which gives the dominant contributions. We emphasize that the charged Higgs effects, with the complex right-handed quark mixing matrix, can account for both     ${R}_{D}$   and     ${R}_{{D}^{\ast }}$   anomalies simultaneously, while adhering to a set of significant constraints including, for instance,     $\text{BR}\left({B}_{c}^{-}\to {\tau }^{-}{\overline{\nu }}_{\tau }\right)$   and     ${B}_{s\left(d\right)}-{\overline{B}}_{s\left(d\right)}$   mixing. In relation to this, we show that the predicted values of the     ${D}^{\ast }$  ,     $\tau $   longitudinal polarizations and     ${P}_{\tau }\left(D\right)$   can be affected for the set of the parameters of the model resolving the     ${R}_{D,{D}^{\ast }}$   anomalies.</dc:description>
