Abstract
Using events collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center, we measure the color-favored branching fractions , , and , where the first error is statistical and the second is systematic. With these results and the current world average for the branching fraction for the color-suppressed decay , the cosines of the strong phase difference between the and isospin amplitudes are determined to be for the process and for the process. Under the isospin symmetry, the results for suggest the presence of final-state interactions in the system.
