Abstract

The semileptonic

B

decay,

{\bar{B}}^{0} \to π^{+} l^{-} v

, is studied in a nonrelativistic picture by treating the pion correctly as a quasi-Nambu-Goldstone boson. The branching ratio is much larger than the value predicted by a two-body bound-state picture for the pion. This decay at the

Y (4 S)

peak in

e^{+} e^{-}

annihilation will be one of the best suited processes to determine the Kobayashi-Maskawa mixing-matrix element

V_{bu}
