Measurement of CP asymmetries and branching fractions in charmless two-body B-meson decays to pions and kaons

We present improved measurements of CP-violation parameters in the decays B0→π+π−, B0→K+π−, and B0→π0π0, and of the branching fractions for B0→π0π0 and B0→K0π0. The results are obtained with the full data set collected at the Υ(4S) resonance by the BABAR experiment at the PEP-II asymmetric-energy B...
