Abstract
Using a sample of events collected with the BABAR detector at the PEP-II factory we study the decay where the is either from a Cabibbo-favored decay or doubly-suppressed decay. We measure two observables that are sensitive to the Cabibbo-Kobayashi-Maskawa angle ; the ratio of the charge-averaged branching fractions for the suppressed and favored decays; and the charge asymmetry of the suppressed decays: , .
