Abstract

We have studied two-body charmless hadronic decays of B mesons into the final states ΠΠKΠand KK. Using 3.3 × 10 BB¯ pairs collected with the CLEO-II detectorwe have made the first observation of the decay B → K Π the sum of B → Π Π and B → K Π decaysand see strong evidence for the decay B → K Π (an average over charge-conjugate states is always implied). We place upper limits on branching fractions for the remaining decay modes. © 1998 The American Physical Society. 6 0 + - + + 0 + + 0 + 0 +
