Aubert, B. et al. (2004) Measurements of moments of the hadronic mass distribution in semileptonic B decays. Physical Review D, 69 (11). p. 111103. ISSN 1550-7998

We report a measurement of the first four moments of the hadronic mass distribution in B̅ →Xcl-ν̅ decays. The measurements are based on 89 million Υ(4S)→BB̅ events where the hadronic decay of one of the B mesons is fully reconstructed and a charged lepton from the decay of the other B meson is identified. The moments are presented for minimum lepton momenta ranging from 0.9 to 1.6 GeV in the B rest frame. It is expected that such measurements will lead to improved determinations of |Vcb| and |Vub|.
