We present a summary of measurements sensitive to the CKM angles \phi_1 and \phi_2, performed by the Belle experiment using the final data sample of 772 \times 10^{6} $B\bar{B}$ pairs at the \Upsilon(4S) resonance produced at the KEK…
We report the measurements of branching fractions and CP violation asymmetries in $B^0 \to \phi K^{*}$ decays obtained in an angular analysis using the full data sample of $772 \times 10^6 B\bar{B}$ pairs collected at the $\Upsilon(4S)$…
Using the full data sample collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, we present three recent measurements of time-dependent CP violation in $B$ decays, and a measurement of branching fraction of the…

We report measurements of CP violation parameters in $B^0 \to K^0 \pi^0$ decays based on a data sample of $657 \times 10^6 B\bar{B}$ pairs collected with the Belle detector at the KEKB $e^+ e^-$ asymmetric-energy collider. We use $B^0 \to…
We report the measurement of the branching fraction and $CP$ asymmetry for the $\bar{B}^{0}(B^{0})\to K^{0}_{S}K^{\mp}\pi^{\pm}$ decay. The analysis is performed on a data sample of 711 $\rm{fb}^{-1}$ collected at the $\Upsilon(4S)$…
The Belle experiment at the KEK $B$ factory has collected 93 fb$^{-1}$ of electron positron collisions at $\sqrt s = 10.6$ GeV. This has produced a sample of 85 million $B {\bar B}$ meson pairs that can be used to study $CP$ violation in…
We measure the branching fraction and $CP$ violation asymmetry in the decay $B^{0}\to \pi^{0}\pi^{0}$, using a data sample of $752\times 10^{6}$ $B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB…
We report measurements of the branching fractions and CP asymmetries for B^+- -> eta h^+- (h = K or pi) and the observation of the decay B^0 -> eta K^0 from the final data sample of 772x10^6 BBbar pairs collected with the Belle detector at…
We present new measurements of CP-violation parameters in B0 --> phi K0, K+ K- Ks, f0(980) Ks, eta' Ks, omega Ks, Ks pi0, and K*0 gamma (K*0 --> Ks pi0) decays based on a sample of 275 x 10^6 BBbar pairs collected at the Upsilon(4S)…
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…
$CP$ violation and branching fraction measurements in $D$ decays are interesting topics as any difference with respect to the Standard Model prediction would be an indication of new physics. With the large data sample collected by the Belle…

We report the measurement of branching fractions and $CP$-violation asymmetries in $B\to \phi \phi K$ decays based on a $711\,{\rm fb}^{-1}$ data sample containing $772\times 10^6$ $B\bar{B}$ events. The data were recorded at the $\Upsilon…
We report the recent measurements of $B^0\to J/\psi\pi^0$ and other CP violation modes based on the data collected by the Belle experiment at the KEKB collider. The CP asymmetry parameters for the decay $B^0\to J/\psi\pi^0$ have previously…
We present a measurement of the branching fraction and the longitudinal polarization fraction of $B^{0}\rightarrow\rho^+\rho^-$ decays, as well as the time-dependent $CP$ violating parameters in decays into longitudinally polarized…
Hadronic $B$ decays without a charm quark constitute a powerful probe to search for physics beyond the standard model as well as to provide constraints on $CP$ violation parameters. We report final measurements from Belle of the branching…
