    Study of exclusive B -> X(u)lv decays and extraction of vertical bar V-ub vertical bar using full reconstruction tagging at the Belle experiment

  • Original language description

    We report the results of a study of the exclusive semileptonic decays B- -> pi(0)l(-)(v) over bar (l), (B) over bar (0) -> pi(+)l(-)(v) over bar (l), B- -> rho(0)l(-)(v) over bar (l), (B) over bar (0) -> rho+l(-)(v) over bar (l) and B- -> omega l(-)(v) over bar (l), where l represents an electron or a muon. The events are tagged by fully reconstructing a second B meson in the event in a hadronic decay mode. The measured branching fractions are 'B(B- -> pi(0)l(-)(v) over bar (l)) = (0.80 +/- 0.08 +/- 0.04 x 10(-4), B((B) over bar (0) -> pi(0)l(-)(v) over bar (l)) = (1.49 +/- 0.09 +/- 0.07) x 10(-4), B(B- -> rho(0)l(-)(v) over bar (l)) = 1.83 +/- 0.10 +/- 0.10 x 10(-4), B((B) over bar (0) -> rho(0)l(-)(v) over bar (l) 3.22 +/- 0.27 +/- 0.24) x 10(-4), and B(B- -> omega l(-)(v) over bar (l)) = 1.07 +/- 0.16 +/- 0.07) x 10(-4), where the first error is statistical and the second one is systematic. The obtained branching fractions are inclusive of soft photon emission. We also determine the
