Abstract

We have studied semileptonic B meson decays with a p-wave charm meson in the final state using 3.29×106BB¯ 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−ν¯ℓ)B(D10→D*+π−) = (0.373±0.085±0.052±0.024)% and an upper limit for B(B−→D2*0ℓ-ν¯ℓ)B(D2*0→D*+π−)<0.16% (90% C.L.).Furthermore, we present the first measurement of the q2 spectrum for B−→D10ℓ−ν¯ℓ.
