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