Abstract
We present results from an analysis of decays using pairs collected by the BABAR detector at the PEP-II asymmetric-energy factory at SLAC. The measurements of the branching fraction, longitudinal polarization fraction , and the -violating parameters and are as follows: , , , . We determine the unitarity triangle angle , using an isospin analysis of decays. One of the two solutions, at 68% confidence level, is compatible with standard model-based fits of existing data. Constraints on the unitarity triangle are also evaluated using an symmetry-based approach.
