Phys. Rev. Lett. 62, 2436–2439 (1989)Search for b→u transitions in exclusive hadronic B-meson decaysReceived 16 February 1989; published in the issue dated 22 May 1989 From a data sample of 242 000 BB¯ pairs collected with the CLEO detector at the Υ(4S) resonance, we set upper limits for the branching ratios for exclusive hadronic decays of B mesons arising from b→u transitions. Model-dependent limits for the ratio of the Kobayashi-Maskawa matrix elements Vub/Vcb are presented. © 1989 The American Physical Society URL:
