Observation of B → K±π0 and B → K0π0, and evidence for B → π++π-

Abstract:
We have studied charmless hadronic decays of B mesons into two-body final states with kaons and pions and observe three new processes with the following branching fractions: ℬ(B → π+π-) = (4.3-1.4+1.6 ± 0.5) × 10-6, ℬ(B → K0π0) = (14.6-5.1-3.3+5.9+2.4) × 10-6, and ℬ(B → K±π0) = (11.6-2.7-1.3+3.0+1.4) × 10-6. We also update our previous measurements for the decays B → K±π∓ and B± → K0π±. © 2000 The American Physical Society.
