Abstract

The recent Belle collaboration measurements of B decays to open and hidden charm are discussed. Color-suppressed decay branching fractions are measured with an improved accuracy. The branching fractions of the $\bar{B}^0 \to D_s^+ K^-$ and $\bar{B}^0 \to D_s^- \pi^+$ decays, measured with improved accuracy, and $\bar{B}^0 \to D_{sJ}^+ K^-$ and $\bar{B}^0 \to D_{sJ}^- \pi^+$ decays, measured for the first time, are compared. The two-body invariant masses of the three-body $B^0 \to D^{(*)0} \pi^+ \pi^-$ and $B^0 \to J/\Psi \pi^+ \pi^-$ decays are studied.
