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 {Mathematical expression}, where ℓ^- is either e^- or μ^-, has been measured to be (5.2±0.5±0.6)%. A significant rate for the decay {Mathematical expression} has been observed. From an angular analysis of the cascade {Mathematical expression} 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.
