title = "Measurement of the relative B- →D0/D∗0/D∗∗0μ- ν̅μ branching fractions using B- mesons from B̅s2∗0 decays",
abstract = "The decay of the narrow resonance B̅s2∗0→B-K+ can be used to determine the B- momentum in partially reconstructed decays without any assumptions on the decay products of the B- meson. This technique is employed for the first time to distinguish contributions from D0, D∗0, and higher-mass charmed states (D∗∗0) in semileptonic B- decays by using the missing-mass distribution. The measurement is performed using a data sample corresponding to an integrated luminosity of 3.0 fb-1 collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV. The resulting branching fractions relative to the inclusive B-→D0Xμ-ν̅μ are fD0=ℬ(B-→D0μ-ν̅μ)/ℬ(B-→D0Xμ-ν̅μ)=0.25±0.06, fD∗∗0=ℬ(B-→(D∗∗0→D0X)μ-ν̅μ)/ℬ(B-→D0Xμ-ν̅μ)=0.21±0.07, with fD∗0=1-fD0-fD∗∗0 making up the remainder.",
