Abstract |
We present here the sensitivity study of the rare decay modes and , at Belle using a simulated sample. The {\sc BaBar} collaboration has measured the branching fraction with a data sample of events collected at the resonance. The combined data from the Belle and Belle II experiments is five times larger than the previously used. This will allow us to provide an improved measurement of the branching fraction for these decay modes, for a better bound on the ratio of the amplitudes (assuming SU(3) symmetry), which is important input to extract weak phases in the time-dependent measurement of decays. \ In addition, we aim to search for the mode, whose upper limit is provided by the ARGUS collaboration based on events. |
