The Hadronic Recoil Mass Spectrum in Semileptonic B Decays and Extracting |V_{ub}| in a Model-Insensitive Way

I. Bigi, R. David Dikeman, N. Uraltsev

We present an extended discussion of the previously noted possibility to extract |V_{ub}| from an analysis of the hadronic recoil mass spectrum in B->X_u l nu decays. Invariant mas…
