Abstract

By studying lepton-kaon angular correlations in Υ(4S) decays, we have measured the branching ratios for B¯→

K^{+}

X, B¯→

K^{-}

X, B¯→

K^{0}

/K

¯^{0}

X, B¯→

l^{-}

K^{+}

X, B¯→

l^{-}

K^{-}

X, and B¯→

l^{-}

K^{0}

/K

¯^{0}

X. Their values imply that (b→c)/(b→all)=0.98±0.16±0.12.
