Title: Search for CP Violation in D0→π0π0 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 D0¯ 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. Here, we also present an updated measurement of the CP asymmetry in the D0→K$$^{0}_{S}$$π0 decay: ACP(D0 → K$$^{0}_{S}$$π0) = [–0.21±0.16(stat)±0.07(syst)]%.
