- Abstract
- We report measurements of the branching fractions for B0→π+π−, K+π−, K+K−, and K0π0 and B+→π+π0, K+π0, K0π+, and K+K¯ 0, based on 10.4 fb−1 of data collected on the ±(4S) resonance with the Belle detector. We find B(B0→π+π−) = (0.56-0.20-0.05 +0.23+0.04)×10−5, B(B0→K+π-) = (1.93-0.32-0.06 +0.34+0.15)×10−5, B(B+→K+π0) = (1.63-0.33-0.18 +0.35+0.16)×10−5, B(B+→K0π+) = (1.37-0.48-0.18 +0.57+0.19)×10−5, and B(B0→K0π0) = (1.60-0.59-0.27 +0.72+0.25)×10−5. We also set upper limits on the branching fractions for B+→π+π0, B0→K+K-, and B+→K+K¯0. © 2001 The American Physical Society.
