Scientific paper

A review of recent analyses on semileptonic decays of B mesons into charmed final states is given. |Vcb| is extracted both by the Babar and the Belle collaboration from their datasets using inclusively and exclusively reconstructed final states. In addition there are recent results on the determination of exclusive branching fractions to the ground states D and D*, as well as to excited D** states. Those play an important role in understanding the composition of the total decay width. They represent also a sizable fraction of the backgrounds for exclusive analyses and are presented here as well.
