Study of B(0)->pi(0)pi(0), B(+/-)->pi(+/-)pi(0), and B(+/-)-> K(+/-)pi(0) decays, and isospin analysis of B ->pi pi decays
We present updated measurements of the branching fractions and CP asymmetries for B0→π0π0, B±→π±π0, and B±→K±π0. Based on a sample of 383×106 Υ(4S)→BB̄ decays collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, we measure B(B0→π0π0)=(1. 47±0.25±0.12)×10-6, B(B±→π±π0)=(...
