|V_{ub}| from the Spectrum of B->pi e nu

High Energy Physics - Phenomenology 2008-11-26 v1

Abstract

I discuss the results for Vubf+(0)|V_{ub}|f_+(0) and Vub|V_{ub}| obtained from the spectrum of BπeνB\to\pi e \nu and the form factor f+(q2)f_+(q^2) from QCD sum rules on the light-cone and unquenched lattice calculations; the shape of f+(q2)f_+(q^2) is fixed from experimental data.
