Abstract

Exclusive semileptonic B decays with a D*⁺ meson in the final state have been studied using the ARGUS detector at the DORIS II storage ring. The branching ratio for the decay <span style="text-decoration: overline">B</span>⁰ → D*⁺ ℓ^- <span style="text-decoration: overline">v</span>, where <span style="text-decoration: overline">B</span> → D ℓ^- <span style="text-decoration: overline">v</span> has been observed. From an angular analysis of the cascade <span style="text-decoration: overline">B</span>⁰ → D*⁺ (→ D⁰ π ⁺) ℓ^-<span style="text-decoration: overline">v</span> the forward-backward asymmetry A_FB and the D*⁺ polarization parameter α have been determined to be A_FB=0.20±0.08±0.06 and α=1.1±0.4±0.2.
