dc.description.abstract We update the extraction of |V-ub| from exclusive semileptonic B ->pi decays, combining experimental partial branching fraction information with theoretical form-factor calculations, using the recently revised HPQCD results for the form factors f(+) and f(0). We use Omnes representations to provide the required parametrizations of the form factors. The extracted value is |V-ub|=(3.47 +/- 0.29 +/- 0.03)x10(-3), in striking agreement with |V-ub| extracted using all other inputs in CKM fits and showing some disagreement with |V-ub| extracted from inclusive semileptonic B ->pi decays.
