Charmed B decays at Belle

Recent results of B decays to charmed mesons and charmonium states from Belle collaboration are reviewed. The contributions of two-body B→ D ** π decays with narrow (j q =3/2) and broad (j q =1/2) D ** have been determined. We report the first observation of the decay B +→ ψ(3770)K + ($\psi(3770)\to D^0\bar{D^0}$ and D + D –). Also we report the observation of the D sJ (2317) and D sJ (2457) in B decays. PACS: 13.25.Hw – 13.20.Gd – 14.40L
