Estimated of CP violation in B^0 meson decays into D^{*+} and D^- mesons

Abstract

The decay B^0rightarrow D^{*+}D^- is favorable mode for studying CP violation in the interference between mixing and decay for B^0 and bar{B}^0 mesons. The latest analysis of the CP parameters has been performed by the LHCb Collaboration values of S_{D^*D}=-,0.861pm 0.077pm 0.019, C_{D^*D}=-,0.059pm 0.092pm 0.020, triangle S_{D^*D}=0.019pm 0.075pm 0.012, triangle C_{D^*D}=-,0.031pm 0.092pm 0.016, and mathcal {A}_{D^*D}^{CP}=0.008pm 0.014pm 0.006pm 0.003. We have been estimated the parameters S_{D^*D} and C_{D^*D} of the B^0rightarrow D^{*+}D^- decay as -,0.709pm 0.024 and -,0.051pm 0.004. In the following, we have obtained the values of triangle S_{D^*D}=0.054pm 0.003 and triangle C_{D^*D}=0.020pm 0.001 and direct CP violation of 0.008pm 0.001. Also, we have calculated the branching ratio of B^0rightarrow D^{*+}D^- decay. The values obtained in this work are comparable with the corresponding experimental values.
