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: BR(B-> pi+ pi-) = (4.3^+1.6_-1.4 ± 0.5) × 10^-6, BR(B-> K0 pi0) = (14.6^+5.9+2.4_-5.1-3.3) × 10^-6, and BR(B-> K+- pi0) = (11.6^+3.0+1.4_-2.7-1.3) × 10^-6. We also update our previous measurements for the decays B->K+- pi-+ and B-> K0 pi+-.
