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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/120264I discuss the results for $|V_{ub}|$ obtained from $B\toπe ν$ using the form factor $f_+(q^2)$ from QCD sum rules on the light-cone and unquenched lattice calculations; the shape of $f_+(q^2)$ is fixed from experimental data.Talk given at CKM06High Energy Physics - Phenomenology|V_{ub}| from B-> pi e nutext
