Abstract

In these proceedings, we give a summary of the experimental results from CLEO, Belle, BaBar and CDF collaboration about D⁰-D⁰ mixing and CP violation in self-conjugated-three-body decays D⁰→ K_S⁰hh (where h can be π or K). We report preliminary results of measurement of D⁰-D⁰ mixing and indirect CP violation in D⁰→ K_S⁰π⁺π^- decays using full data sample collected by Belle detector at KEKB asymmetric-energy e⁺e^- collider: give values for x=(0.56±0.19^+0.03+0.06_-0.09-0.09)%, y=(0.30±0.15^+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±11⁺³⁺³_-3-4(^o). We also report results of recent measurement searching for CP violation in D⁰→ K_S⁰π⁺π^- decays by CDF collaboration using 6.0 fb^-1 of data collected in pp collisions at Tevatron. The phase-space-integrated CP asymmetry is measured to be A_CP=(-0.05±0.57±0.54)% and the CP symmetry is also found to be conserved in all individual intermediate contributions.
