We report measurements of the CKM angles beta/phi_1 and alpha/phi_2 done by the BABAR and Belle experiments. Both experiments have collected large data samples, corresponding to a total of more than 1 billion of BBbar pairs, at the e^+e^-…

In this proceeding, we report the recent measurements of the CKM angle \phi_1(\beta) using large data samples collected by the Belle and BaBar experiments. The experiments have collected more than 1 billion B anti-B pairs of data sample at…

I review results related to the CKM angle $\phi_1$($\beta$). These results include recent measurements of CP-violation from the BaBar and Belle experiments in $b\to c \bar{c} s$, $b\to c \bar{c} d$ and $b\to s q \bar{q}$ processes.

We report recent results on $\phi_3$ measurement at the Belle collaboration. The analyses reported here are based on a large data sample that contains 657 million $B\bar{B}$ pairs collected with the Belle detector at the KEKB…

The CKM angle $\gamma/\phi_{3}$ had been measured by two B-factories, the PEPII collider for the BaBar experiment and the KEKB collider for the Belle experiments. The present paper reports recent progress in $\gamma/\phi_{3}$.

We present a summary of the measurements of the CKM angle, alpha (phi2), performed by the BaBar and Belle experiments which collect BBbar pairs at the Y(4S) resonance produced in asymmetric e+ e- collisions. We discuss the measurements of…

We present measurements related to the CKM angle beta from BABAR based on 82 or ~115 fb-1 data samples collected at the PEP-II e+e- asymmetric B Factory collider. A new method allowing to measure the sign of cos(2.beta) with B0->J/Psi"K*0"…

In this review recent studies on $CP$ violation and related hadronic $B$ decays by the Belle experiment, in particular measurements of CKM angles $\phi_1$ and $\phi_2$ are reported.

The Belle experiment has used several methods to measure or constrain the angles phi_1, phi_2, and phi_3 (or beta, alpha, and gamma) of the CKM unitarity triangle. The results are sin(2phi_1) = 0.728 \pm 0.056 (stat) \pm 0.023 (syst) or…

The Belle and BaBar experiments have measured branching fractions and CP asymmetries in the charmless decay modes B0->pi+pi-, B0->rho+pi-/rho-pi+, and B0->rho+rho-. From these measurements, constraints upon the CKM angle phi_2 can be…

We present a summary of measurements sensitive to the CKM angle \phi 2 (\alpha), performed by the BaBar and the Belle experiments which both collect B\bar{B} pairs produced at the \Upsilon(4S) resonance in asymmetric e+e- collisions. We…

We present recent measurements of the unitarity triangle angle phi2(alpha) using B -> pi pi, B -> rho rho, and B -> rho pi decays. The measurements are based on data samples collected with the Belle and BaBar detectors at the KEKB and…

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…

The precise measurement of the CKM angle $\phi_3$ is important to further test the Standard Model description of $CP$ violation. The small values of the branching fractions of the decays involved in the measurement limits the precision,…

We present a review of the measurements of the CKM angle beta (phi_1) by the BaBar and Belle experiments at the asymmetric-energy e+e- B Factories PEP-II and KEKB. The angle beta (phi_1) is measured by time-dependent CP analyses of neutral…

The BELLE detector has already accumulated e^+ e^- collision data at the KEKB-collider corresponding to 600 fb^-1. BaBar has accumulated data of approximately 390 fb^-1 at PEP-II. Both are running on asymmetric energy e^+ e^- colliders at…
