Phys. Rev. Lett. 58, 1814–1817 (1987)Branching ratios of B mesons to K+,K-, and K0/K¯0Received 29 December 1986; published in the issue dated 4 May 1987 By studying lepton-kaon angular correlations in Υ(4S) decays, we have measured the branching ratios for B¯→K+X, B¯→K-X, B¯→K0/K¯0X, B¯→l-K+X, B¯→l-K-X, and B¯→l-K0/K¯0X. Their values imply that (b→c)/(b→all)=0.98±0.16±0.12. © 1987 The American Physical Society URL:
