Measurement of the B̄0 → D *+ℓ-ν̄ℓ decay rate and |Vcb|

Measurement of the B̄0 → D *+ℓ-ν̄ℓ decay rate and |Vcb|

We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element |Vcb| based on a sample of about 53 700 B̄0 → D*+ℓ-ν̄ℓ decays observed by the BABAR detector. We obtain the branching fraction averaged over ℓ = e, μ, B(B̄0 → D*+ℓ -ν̄ℓ) = (4.90 ± 0.07(stat.) -0.35+0.36(syst.))%. We measure the...
