Abstract: We report a measurement of time-dependent CP violation in B0?KS0?0?0 decays using a data sample of 772�106 BB pairs collected by the Belle experiment running at the ?(4S) resonance at the KEKB e+e- collider. This decay proceeds mainly via a b?sdd "penguin" amplitude. The results are sin2?1eff=0.92-0.31+0.27 (stat.) �0.11 (syst.) and A=0.28�0.21 (stat.) �0.04 (syst.), which are the most precise measurements of CP violation in this decay mode to date. The value for the CP-violating parameter sin2?1eff is consistent with that obtained using decay modes proceeding via a b?ccs "tree" amplitude. � 2019 authors.
