Measurement of the Relative Branching Fractions for B- -> D/D*/D**(D(*)pi) l- anti-nu with a Large Sample of Tagged B Mesons

The BABAR Collaboration, B. Aubert

We present a study of B semileptonic decays into charm final states based on 211.7 fb^{-1} of data collected at the Υ(4S) resonance with the babar detector at the pep2 e^+e^- stora…
