Abstract

We present measurements, based on a sample of approximately 23×106 BB̅ pairs, of the branching fractions and a search for CP-violating charge asymmetries in charmless hadronic decays of B mesons into two-body final states of kaons and pions. We find the branching fractions B(B0→π+π-) = (4.1±1.0±0.7)×10-6, B(B0→K+π-) = (16.7±1.6±1.3)×10-6, B(B+→K+π0) = (10.8-1.9+2.1±1.0)×10-6, B(B+→K0π+) = (18.2-3.0+3.3±2.0)×10-6, B(B0→K0π0) = (8.2-2.7+3.1±1.2)×10-6. We also report 90% confidence level upper limits for B meson decays to the π+π0, K+K-, and K̅ 0K+ final states. In addition, charge asymmetries have been found to be consistent with zero, where the statistical precision is in the range of ±0.10 to ±0.18, depending on the decay mode.
