  "abstract": "<p>We investigate     ${R}_{D}$   and     ${R}_{{D}^{\\ast }}$   anomalies in a low scale left\u2013right symmetric model based on     $SU{\\left(3\\right)}_{C}\u00d7SU{\\left(2\\right)}_{L}\u00d7SU{\\left(2\\right)}_{R}\u00d7U{\\left(1\\right)}_{B-L}$   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     ${H}^{\u00b1}$   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.</p>",
