Abstract

Recent B meson semi leptonic branching ratio measurements are summarized and appear to be lower than theoretical expectations. Measurements of the exclusive final states Doe-ν, D*oe-ν, D*+e-ν and D**e-ν are reported. The ratio of rates D*o and the polarization of the D*+ are shown to be consistent with theoretical models. Finally comparing the D*oe-ν and D*+e-ν rates, the lifetime ratio of neutral and charged B's is shown to be equal to 1.18±0.27+0.22-0.30.
