D^0-\bar{D}^0 Mixing and CP Violation in D^0-->K_{S}hh measurements

Abstract

In these proceedings, we give a summary of the experimental results from CLEO, Belle, BaBar and CDF collaboration about $D^0-{\bar{D}}^0$ mixing and CP violation in self-conjugated-three-body decays $D^0\to K_S^{0}hh$ (where $h$ can be $\pi$ or $K$). We report preliminary results of measurement of $D^0-{\bar{D}}^0$ mixing and indirect CP violation in $D^0\to K_S^0{\pi }^{+}{\pi }^{-}$ decays using full data sample collected by Belle detector at KEKB asymmetric-energy $e^{+}{e}^{-}$ collider: give values for $x=(0.56\pm 0.19_{-0.09-0.09}^{+0.03+0.06})$, $y=(0.30\pm 0.15_{-0.05-0.06}^{+0.04+0.03})$, $|q/p|=0.90_{-0.15-0.04-0.05}^{+0.16+0.05+0.06}$ and $\arg (q/p)=-6\pm 11_{-3-4}^{+3+3}{(}^o)$. We also report results of recent measurement searching for CP violation in $D^0\to K_S^0{\pi }^{+}{\pi }^{-}$ decays by CDF collaboration using $6.0f{b}^{-1}$ of data collected in $p\bar{p}$ collisions at Tevatron. The phase-space-integrated CP asymmetry is measured to be $A_{CP}=(-0.05\pm 0.57\pm 0.54)$ and the CP symmetry is also found to be conserved in all individual intermediate contributions.
