Abstract
We present a study of the decay and its charge conjugate, where is reconstructed in both a non- flavor eigenstate and in (-even and -odd) eigenstates, based on a sample of 382 million decays collected with the BABAR detector at the PEP-II storage ring. We measure the direct asymmetries and the ratios of the branching fractions : , , , . We also express the results in terms of the so-called Cartesian coordinates , , and : , , . These results will help to better constrain the phase parameter of the Cabibbo-Kobayashi-Maskawa quark mixing matrix.
