【 摘 要 】

The authors present improved measurements of the branching fractions and CP asymmetries in the two-body decays B(sup 0) (yields) (pi)(sup 0)(pi)(sup 0), B(sup 0) (yields) K(sup 0)(pi)(sup 0) and B(sup 0) (yields) K(sup +)(pi)(sup -) as well as the quasi two-body B(sup 0) (yields) K(sub 1)(1270)(sup +) (pi)(sup -) and B(sup 0) (yields) K(sub 1)(1400)(sup +) (pi)(sup -) decays. These updated measurements are made using the complete set of BABAR data taken at the Y(4S) resonance, collected between 1999 and 2007 at the PEP-II collider at SLAC.
