Moments of the Electron Energy Spectrum in Semileptonic B Decays at Belle
Abstract
We report a measurement of the inclusive electron energy spectrum for semileptonic decays of B mesons in a 140 fb-1 data sample collected near the Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric energy e+ e- collider. We determine the first and second moments of the spectrum for threshold values of the electron energy between 0.6 and 1.5 GeV.
