abstract

  • We report on determinations of [Formula Presented] resulting from studies of the branching fraction and [Formula Presented] distributions in exclusive semileptonic B decays that proceed via the [Formula Presented] transition. Our data set consists of the [Formula Presented] [Formula Presented] meson pairs collected at the [Formula Presented] resonance with the CLEO II detector. We measure [Formula Presented] and [Formula Presented] where the errors are statistical, experimental systematic, systematic due to residual form-factor uncertainties in the signal, and systematic due to residual form-factor uncertainties in the cross-feed modes, respectively. We also find [Formula Presented] consistent with what is expected from the [Formula Presented] mode and quark model symmetries. We extract [Formula Presented] using light-cone sum rules for [Formula Presented] and lattice QCD for [Formula Presented] Combining both intervals yields [Formula Presented] for [Formula Presented] and [Formula Presented] for [Formula Presented] where the errors are statistical, experimental systematic, theoretical, and l form-factor shape, respectively. Our combined value from both decay modes is [Formula Presented] 2003 The American Physical Society.
