Abstract: (Elsevier)

Using the ARGUS detector at the e + e − storage ring DORIS II, we have investigated the decay B 0 →D − ℓ + ν, where ℓ + is e + or μ + . The B 0 mesons were produced in 150 000 ϒ(4S) decays. Assuming electron-muon universality we obtain a branching ratio BR(B 0 →D − e + ν )=BR(B 0 →D − μ + ν )=(1.8±0.6±0.5)%.
