Scientific paper

We report results of measurement of the unitarity triangle angle $\phi_3$ with $B^+\rightarrow D^{(*)}K^+$ Dalitz plot analysis and related issues with $B^0 \rightarrow D_s^{*+} \pi^-$ and $B^0 \rightarrow D_s^{*-} K^+$ decay processes. The Dalitz analysis improves accuracy of the angle $\phi_3$ as $78.4^\circ ~^{+10.8^\circ}_{-11.6^\circ}\pm 3.6^\circ\pm 8.9^\circ$ and the branching fractions are found to be $B^0 \rightarrow D_s^{*+} \pi^-(K^-)$ decays are set as $\mathcal{B}(B^0 \rightarrow D_s^{*+} \pi^-) = (1.75 \pm 0.34 (\mathrm{stat}) \pm 0.17(\mathrm{syst}) \pm 0.11(\mathcal{B})) \times 10^{-5}$ and $\mathcal{B}(B^0 \rightarrow D_s^{*-} K^+) = (2.02 \pm 0.33 (\mathrm{stat}) \pm 0.18({\rm syst}) \pm 0.13(\mathcal{B})) \times 10^{-5}$.
