We present preliminary updated global fits to the moments of semileptonic B decay distributions and extract |Vcb| in addition to the heavy quark masses (mb, mc), and non-perturbative heavy quark expansion parameters (μπ, μG, ρD, ρLS ). Included are both NNLO perturbative corrections and presently calculated perturbative corrections to the power sup- pressed operators. We also discuss briefly the method of integration used to compute the O(αsΛ2QCD/m2b) corrections.

Abstract

We present preliminary updated global fits to the moments of semileptonic B decay distributions and extract |Vcb| in addition to the heavy quark masses (mb, mc), and non-perturbative heavy quark expansion parameters (μπ, μG, ρD, ρLS ). Included are both NNLO perturbative corrections and presently calculated perturbative corrections to the power sup- pressed operators. We also discuss briefly the method of integration used to compute the O(αsΛ2QCD/m2b) corrections.
