Determination of V_ub from semileptonic B decays

High Energy Physics - Phenomenology 2010-11-23 v2

Abstract

The hadronic mass distribution in semileptonic B-meson decays can be used for extracting the charmless part and thus determining the |V_ub/V_cb| ratio. We take into account first-order perturbative as well as non-perturbative QCD corrections. The sensitivity to model assumptions is studied and an estimate of the remaining uncertainties is performed.
