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 3.29×10^6 BB̅ 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^-→D_1^0ℓ^-ν̅ _ℓ)B(D_1^0→D^(*+)π^-) = (0.373±0.085±0.052±0.024)% and an upper limit for B(B^-→D_2^(*0)ℓ^-ν̅_ℓ)B(D_2^(*0)→D^(*+)π^-)<0.16% (90% C.L.). Furthermore, we present the first measurement of the q^2 spectrum for B^-→D_1^0ℓ^-ν̅_ℓ.
