We report a measurement of the first four moments of the hadronic mass distribution in (B) over bar -->X(c)l(-)(v) over bar decays. The measurements are based on 89 million Y(4S)-->B(B) over bar 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 \V-cb\ and \V-ub\.

Abstract

We report a measurement of the first four moments of the hadronic mass distribution in (B) over bar -->X(c)l(-)(v) over bar decays. The measurements are based on 89 million Y(4S)-->B(B) over bar 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 \V-cb\ and \V-ub\.
