A preliminary Measurement of Hadronic Mass Moments in Semileptonic B Meson Decays
arXiv:hep-ex/0307073
Abstract
A preliminary measurement of the second moments of the hadron mass in B --> X l nu decays by the BABAR Collaboration is reported. These measurements are performed as a function of the lepton momentum above a given threshold.
