Measurements of Moments of the Hadronic Mass Distribution in Semileptonic B Decays
- SLAC
We report a measurement of the first four moments of the hadronic mass distribution in {bar B} {yields} X{sub c}{ell}{sup -} {bar {nu}} decays. The measurements are based on 89 million {Upsilon}(4S) {yields} B{bar B} 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{sub cb}| and |V{sub ub}|.
