Abstract

The decay chain b→B¯→D∗∗0ℓ−ν¯X,D∗∗0→D∗+π−,D∗+→D0π+,D0→(KπorK3π) is identified in a sample of 3.9 million hadronic Z decays collected with the OPAL detector at LEP. The branching ratio BR (b→B¯)×BR(B¯→D01ℓ−ν¯X)×BR(D01→D∗+π−) is measured to be (2.64±0.79(stat)±0.39(syst))×10−3 for the JP=1+ (D01) state. For decays into the JP=2+ (D2*0) state, an upper limit of 1.4 x 10-3 is placed on the branching ratio at the 95% confidence level.
