title = "Search for CP Violation in D0 → π0 π0 Decays",
abstract = "We search for CP violation in neutral charm meson decays using a data sample with an integrated luminosity of 966 fb-1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider. The asymmetry obtained in the rate of D0 and D¯0 decays to the π0π0 final state, [-0.03 ± 0.64(stat) ± 0.10(syst)]%, is consistent with no CP violation. This constitutes an order of magnitude improvement over the existing result. We also present an updated measurement of the CP asymmetry in the D0 → K0 Sπ0 decay: ACP (D0 → K0 Sπ0) [-0.21 ± 0.16(stat) ± 0.07(syst)]%.",
