Investigation of semileptonic B meson decays to p-wave charm mesons

Abstract:
We have studied semileptonic B meson decays with a p-wave charm meson in the final state using 3.29 × 106 BB̄ events collected with the CLEO II detector at the Cornell Electron-Positron Storage Ring. We find a value for the exclusive semileptonic product branching fraction ℬ(B- → D10ℓ ν̄ℓ)ℬ(D10 → D*+π-) = (0.373 ± 0.085 ± 0.052 ± 0.024)% and an upper limit for ℬ(ℬ- → D2*0ℓ-ν̄ ℓ)ℬ(D2*0 → D*+π) < 0.16% (90% C.L.). Furthermore, we present the first measurement of the q2 spectrum for B- → D10ℓ-ν̄ℓ.
