Measurement of the moments of the hadronic invariant mass distribution in semileptonic B decays Academic Article uri icon

abstract

  • Using 180 pb -1 of data collected with the CDF II detector at the Tevatron, we measure the first two moments of the hadronic invariant mass-squared distribution in charmed semileptonic B decays. From these we determine the nonperturbative Heavy Quark Effective Theory parameters and 1 used to relate the B meson semileptonic branching ratio to the CKM matrix element |V cb|. For a minimum lepton momentum of 0.7 GeV/c in the B rest frame we measure the first two moments of the D** D (*) component to be m D**2 = (5.83 0.16 stat 0.08 syst) GeV 2/c 4 and (m D**2 - m D**2) 2 = (1.30 0.69 stat 0.22 syst) GeV 4/c 8. Combining these with the discrete mass terms from the D and D* mesons, we find the total moments to be M c2 - m D2 = (0.467 0.038 stat 0.068 syst GeV 2/c 4 and (M c2 - M c2) 2 = (1.05 0.26 stat 0.13 syst) GeV 4/c 8, where m D is the spin-averaged D mass. The systematic error is dominated by the uncertainties in the world-average branching ratios used to combine the D, D*, and D** contributions. The analysis makes no assumptions about the shape or resonant structure of the D** D (*) invariant mass distribution. 2005 The American Physical Society.
