Electron Identification and Measurement of the Inclusive Semileptonic Branching Fraction of B Mesons at the BABAR Experiment
… der Lebenszeit von B-Mesonen lässt sich daraus |V_cb| bestimmen: |V_{cb}| = 0.0406 +-0.0009(exp) +-0.0019(theory).

Reconstruction of B- --> D*° e- nu Decays and Determination of |Vcb|
In this analysis the decay B- --> D*° e- nu is measured. The underlying data sample consists of about 226 million B-meson pairs accumulated on the Y(4S) resonance by the BABAR detector at the asymmetric e+e- collider PEP II. The reconstruction of the decay uses the channels D*° --> D° pi°, D° …
