Moments of the Hadronic Invariant Mass Spectrum in B --> Xc l nu Decays at Belle
Abstract
We present a measurement of the hadronic invariant mass squared (M2X) spectrum in charmed semileptonic B meson decays B --> Xc l nu based on 140 fb-1 of Belle data collected near the Y(4S) resonance. We determine the first, the second central and the second non-central moments of this spectrum for lepton energy thresholds ranging between 0.7 and 1.9 GeV. Full correlations between these measurements are evaluated.
