Determination of $V_{ub}$ from semileptonic B decays
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 es...
