Description
We report results of the branching fractions $\mathcal{B}(\bar{B}^0\to D^{*+}\pi^{-})$ and $\mathcal{B}(\bar{B}^0\to D^{*+}K^{-})$ measured using $772\times 10^{6}$ $B$-meson pairs recorded by the Belle experiment at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The measurements provide a precise test of QCD factorization. We also report the study of the branching fraction $B^+ \to D_s^{(*)}(\eta,K_S) / D^+(\eta,K_S)$ and the time-dependent CP asymmetry in $B \to \eta_c K_S$. The latter measurement provides information about $\sin{2\phi_1}$.
