Abstract

We report on recent measurements of the D0Dˉ0D^0-\bar{D}^0 mixing and CPCP violation parameters performed by the Belle experiment. The evidence for the mixing phenomena in the system of neutral DD mesons, arising in the study of D0K+K,π+πD^0\to K^+K^-, \pi^+\pi^- decays is presented first. Using a time dependent Dalitz analysis of D0KSπ+πD^0\to K_S\pi^+\pi^- decays we also obtained the most precise up-to-date determination of the mass difference of the two DD meson mass eigenstates. The presented results are based on 540 fb1^{-1} of data recorded by the Belle detector at the KEKB e+ee^+e^- collider. We conclude with short prospects for the future measurements.
