Abstract
Using of data from the Belle experiment recorded at or near the resonance, we have measured the rates of the “wrong-sign” decays and relative to those of the Cabibbo-favored decays and . These wrong-sign decays proceed via a doubly Cabibbo-suppressed amplitude or via mixing; the latter has not yet been observed. We obtain and . The asymmetries are measured to be and for the and final states, respectively.
