Abstract

We report a preliminary study of the branching fractions and q² distributions of exclusive charmless semileptonic B decays, using events tagged by fully reconstructing one of the B mesons in a hadronic decay mode. These results are obtained from a data sample that contains 535 × 10⁶ BB pairs, collected near the Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e⁺ e^- collider.
