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 10.4fb−1 of data collected on the ϒ(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.
