Abstract
We report a measurement of time-dependent violation in decays using a data sample of pairs collected by the Belle experiment running at the resonance at the KEKB collider. This decay proceeds mainly via a “penguin” amplitude. The results are (stat.) (syst.) and (stat.) (syst.), which are the most precise measurements of violation in this decay mode to date. The value for the -violating parameter is consistent with that obtained using decay modes proceeding via a “tree” amplitude.
