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 $D^0\rightarrow K_S^0hh$ (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 $D^0\rightarrow K_S^0\pi^+\pi^-$ decays using full data sample collected by Belle detector at KEKB asymmetric-energy $e^+e^-$ collider: give values for $x=(0.56\pm0.19^{+0.03+0.06}_{-0.09-0.09})%$, $y=(0.30\pm0.15^{+0.04+0.03}_{-0.05-0.06})%$, $|q/p|=0.90^{+0.16+0.05+0.06}_{-0.15-0.04-0.05}$ and $\arg(q/p)=-6\pm11^{+3+3}_{-3-4}(^o)$. We also report results of recent measurement searching for CP violation in $D^0\rightarrow K_S^0\pi^+\pi^-$ decays by CDF collaboration using $6.0 fb^{-1}$ of data collected in $p\bar{p}$ collisions at Tevatron. The phase-space-integrated CP asymmetry is measured to be $A_{CP}=(-0.05\pm0.57\pm0.54)%$ and the CP symmetry is also found to be conserved in all individual intermediate contributions.
