title = "Measurement of the B → Dℓν branching fractions and form factor",
abstract = "Using a sample of 3.3 × 106 B-meson decays collected with the CLEO detector at the Cornell Electron Storage Ring, we have studied B- → D0ℓ-ν and B0 → D+ℓ-ν decays, where ℓ- can be either e- or μ-. We distinguish B → Dℓν from other B semileptonic decays by examining the net momentum and energy of the particles recoiling against D - ℓ pairs. We find Γ(B → Dℓν) = (14.1±1.0±1.2)ns-1 and derive branching fractions for B- → D0ℓ-ν and B0 → D+ℓ-ν of (2.32±0.17±0.20)% and (2.20±0.16±0.19)%, respectively, where the uncertainties are statistical and systematic. We also investigate the B → Dℓν form factor and the implication of the result for |Vcb|.",
