Investigating R_D and R_D* anomalies in a left-right model with an inverse seesaw

We investigate R-D and R-D* anomalies in a low scale left-right symmetric model based on SU(3)(C) x SU(2)(L) x SU(2)(R) x U(1)(B-L) with a simplified Higgs sector consisting of only one bidoublet and one SU(2)(R) doublet. The Wilson coefficients relevant to the transition b -> 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* anomalies simultaneously, while adhering to a set of significant constraints including, for instance, BR(B-c(-) -> tau(-)(nu) over bar (tau)) and B-s(d) - (B) over bar (s(d)) mixing. In relation to this, we show that the predicted values of the D-*, tau longitudinal polarizations and P-tau (D) can be affected for the set of the parameters of the model resolving the R-D,R-D* anomalies.
