Abstract:
We have searched for CP violation of charmed mesons in the decays $D\to K^0_S P$, where $D$ denotes $D^0$ and $D^+_{(s)}$, and $P$ denotes the pseudo-scalar mesons $\pi^+$, $K^+$, $\pi^0$, $\eta$, and $\eta'$. No evidence of CP violation in these decays is observed. We also have measured the CP asymmetry difference between the Cabibbo suppressed decay $D^+\to\phi\pi^+$ and the Cabibbo favored $D^+_s\to\phi\pi^+$ decays in the region of $|M(K^+K^-)-M^{\phi}_{PDG}|<$16 MeV/$c^2$. The measured asymmetry is corrected for the residual asymmetry due to detector effects, and the contributions of both CP and forward-backward asymmetries are determined. These results are obtained on a large data sample collected at and near the $\Upsilon(4S)$ resonance with the Belle detector operating at the KEKB asymmetric-energy $e^+e^-$ collider.

Abstract:
Using the full data sample collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, we have searched for CP violation of charmed mesons in $D^+\rightarrow K^0_S\pi^+$ and $D^0\rightarrow h^+h^-$ decays, where $h$ denotes $K$ and $\pi$. We observe evidence for CP violation in $D^+\rightarrow K^0_S\pi^+$ decay with 3.2 standard deviations away from zero, $(-0.363\pm0.094\pm0.067)%$, while the asymmetry is consistent with the expected CP violation due to the neutral kaon in the final state. No evidence for CP violation in $D^0\rightarrow h^+h^-$ is observed with $A^{KK}_{CP}=(-0.32\pm0.21\pm0.09)%$ and $A^{\pi\pi}_{CP}=(+0.55\pm0.36\pm0.09)%$. The CP asymmetry difference between $D^0\rightarrow K^+K^-$ and $D^0\rightarrow\pi^+\pi^-$ decays is also measured with $\Delta A^{hh}_{CP}=(-0.87\pm0.41\pm0.06)%$, which is 2.1 standard deviations away from zero and supports recent LHCb and CDF measurements.

Abstract:
We present charm CP violation and mixing measurements at Belle. They are the first observation of $D^0-\bar{D}^0$ mixing in $e^+e^-$ collisions from $D^0\rightarrow K^+\pi^-$ decays, the most precise mixing and indirect CP violation parameters from $D^0\rightarrow K^0_S\pi^+\pi^-$ decays, and the time-integrated CP asymmetries in $D^0\rightarrow\pi^0\pi^0$ and $D^0\rightarrow K^0_S\pi^0$ decays. Our mixing measurement in $D^0\rightarrow K^+\pi^-$ decays excludes the no-mixing hypothesis at the 5.1 standard deviation level. The mixing parameters $x=(0.56\pm0.19^{+0.03+0.06}_{-0.09-0.09})%$, $y=(0.30\pm0.15^{+0.04+0.03}_{-0.05-0.06})%$ and indirect CP violation parameters $|q/p|=(0.90^{+0.16+0.05+0.06}_{-0.15-0.04-0.05})$, arg$(q/p)=(-6\pm11\pm3^{+3}_{-4})^{\circ}$ measured from $D^0\rightarrow K^0_S\pi^+\pi^-$ decays, and the time-integrated CP asymmetries $A^{D^0\rightarrow\pi^0\pi^0}_{CP}=(-0.03\pm0.64\pm0.10)%$ and $A^{D^0\rightarrow K^0_S\pi^0}_{CP}=(-0.21\pm0.16\pm0.07)%$ are the most precise measurements to date. Our measurements here are consistent with predictions of the standard model.

Abstract:
We summarize recent results on an array of CP violation measurements performed by the Belle experiment using the data collected near the Y(4S) and Y(5S) resonances at the KEKB asymmetric-energy e+e- collider.

Abstract:
Although CP violation is predicted to be small in the Standard Model, there exists a continuing theoretical interest within the charm sector due to enhancements of CPV through new physics processes. We present an overview of the measurements of direct CP violation in the charm sector at Belle. We give a brief review of the theory of CP violation in charm physics, then discuss recent measurements for the decay modes $D^{+}_{(s)}\rightarrow \phi\pi^{+}$; $D^{0}\rightarrow K^{0}_{S}\pi^{0}, K^{0}_{S}\eta^{(\prime)}$; $D^{+}\rightarrow \pi^{+}\eta^{(\prime)}$; and $D^{+}\rightarrow K^{0}_{S}\pi^{+}$.

Abstract:
In this proceeding, we report the recent measurements of time-dependent CP violation in B meson decays from the Belle Collaboration. The Belle experiment stopped operation in June 2010 and collected nearly 772 x 10^6 B B-bar pairs at the \Upsilon(4S) resonance at the KEKB asymmetric-energy e^+e^- collider. We used this full data sample to measure the CP violation parameters in b->c c-bar s and b->c c-bar d decays. We also report new measurements of CPT violation parameters in B decays. Furthermore, we report the first observation of a new b->s radiative penguin decay B^0->\phi K^0 \gamma, as well as measurements of its time-dependent CP asymmetry.

Abstract:
We present the study of CP violation in charm and charmonium decays, using a data sample corresponding to 657 \times 10^6 BBbar events collected with the Belle detector at the \Upsilon(4S) resonance at the KEKB asymmetric-energy e^+e^- collider. We report measurements of the polarization fraction and time-dependent CP-violation parameters of the decay B^0\to D^{*+}D^{*-} and of the branching fraction and charge asymmetry in the decay of the Cabibbo- and color-suppressed process B^{\pm} \to \psi(2S) \pi^{\pm}.
