Abstract
We report measurements of the branching fractions for B-0 --> pi (+) pi (-) , K+ pi (-), K+K-, and K(0)pi (0) and B+ --> pi (+) pi (0), K+ pi (0), K-0 pi (+), and K+(K) over bar (0), based on 10.4 fb(-1) of data collected on t he Y (4S) resonance with the Belle detector. We find B(B-0 --> pi (+)pi (-) ) = (0.56(-0.20-0.05)(+0.23+0.04)) x 10(-5), B(B-0 --> K(+)pi (-)) = (1.93( -0.32-0.06)(+0.34+0.15)) x 10(-5), B(B+ --> K(+)pi (0)) = (1.63(-0.33-0.18) (+0.35+0.16)) 10(-5), B(B+ --> K(0)pi (+)) = (1.37(-0.48-0.18)(+0.57+0.19)) x 10(-5), and B(B-0 --> K(0)pi (0)) (1.60(-0.59-0.27)(+0.72+0.25)) x 10(-5 ). We also set upper limits on the branching fractions for B+ --> pi (+) pi (o), B-0 --> K+ K-, and B+ --> K+(K) over bar (0).
