Abstract
We present improved measurements of the branching fraction and asymmetry for the process . The data sample corresponding to comprises decays collected with the BABAR detector at the PEP-II asymmetric Factory at SLAC. The yield and asymmetry are measured using an extended maximum likelihood fitting method. The branching fraction and asymmetry are found to be and .
