Measurement of Semileptonic B Decays into Orbitally Excited Charmed Mesons

Abstract:

We present a study of B decays into semileptonic final states containing charged and neutral D1(2420) and D2*(2460). The analysis is based on a data sample of 208fb-1 collected at the Υ(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. With a simultaneous fit to four different decay chains, the semileptonic branching fractions are extracted from measurements of the mass difference Δm=m(D**)- m(D) distributions. Product branching fractions are determined ...
