Measurement of the B̄ → Dlv̄ Partial width and form factor parameters

We have studied the decay B̄ → Dlv̄, where l = e or μ. From a fit to the differential decay rate dΓ/dw we measure the rate normalization FD(1)|Vcb| and form factor slope ρ̂D2, and, using measured values of τB, find Γ(B̄ → Dlv̄) = (12.0 ± 0.9 ± 2.1) ns-1. The resulting branching fractions are B(B̄0 →...
