The measurement of sin2beta by the BABAR experiment, where beta is one of the angles of the Unitarity Triangle, is described. Some prospects for the future of the measurement are also discussed.
In this article we will review recent BABAR measurements of Unitarity Triangle angle beta in B meson decays to charm and charmonium.
We present several alternative techniques used by the BaBar Collaboration in order to measure the Unitarity Triangle angle gamma. We also present the results of two searches designed to improve the measurements of sin(2beta) using penguin B…
This report summarizes the most recent progress in measuring the angle gamma (or phi_3) of the Unitarity Triangle.
On behalf of the Babar and Belle collaborations, we report on the measurement of the angle gamma and on the sum of angles 2 beta+gamma of the Unitarity Triangle.
This report summarizes the progress in measuring the angle gamma (or phi3) of the Unitarity Triangle.
During the last three decades the determination of the Unitarity Triangle (UT) was dominated by the measurements of its sides $R_b$ and $R_t$ through tree-level $B$ decays and the $\Delta M_d/\Delta M_s$ ratio, respectively, with some…
We report on the initial measurements of the angle gamma and the sum of angles 2 beta + gamma of the Unitarity Triangle. When compared with indirect information on the value of gamma from other measurements of CKM parameters, the…
The measurements of the angle alpha (phi2) of the unitarity triangle at the B factories are reviewed. The value of alpha determined by combining the results obtained in the B to pi pi, B to rho pi, and B to rho rho modes by both the BABAR…
The precise measurements of the Bd oscillation frequency and the limit on the Bs one one as well as the determination of the Cabibbo-Kobayashi-Maskawa matrix element Vub improve the constraints on the other elements of this matrix. A fit to…
We give a status report on measurements of the angle phi_2 (alpha) of the CKM unitarity triangle (UT) and the so-called Kpi puzzle. Results presented are mostly from the two B-factory experiments, Belle and BaBar.
Using the most recent determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constraints come from the measurements of epsilon_k, Vub/Vcb…
In this report we summarize the most recent results of measurements of the angle $\gamma/\phi_3$ of the Unitarity Triangle.
We report recent measurements of the Unitarity triangle angles phi_1 and phi_2 using large data samples collected with Belle and BaBar detectors at e+e- asymmetric-energy colliders.
We present results related to determination of the Unitarity Triangle angle phi_3.
Using the latest determinations of several theoretical and experimental parameters, we update the Unitarity Triangle analysis in the Standard Model. The basic experimental constraints come from the measurements of |V_ub/V_cb|, Delta M_d,…
The unitarity triangle can be determined by means of two measurements of its sides or angles. Assuming the same relative errors on the angles $(\alpha,\beta,\gamma)$ and the sides $(R_b,R_t)$, we find that the pairs $(\gamma,\beta)$ and…
Recent measurements of sin2Beta and cos2Beta using b --> ccbars decays are presented using data collected by the BaBar experiment at the PEP-II asymmetric-energy B-factory.
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…
In this article I report on new and updated measurements of the CP-violating parameter beta (phi_1), which is related to the phase of the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing matrix of the electroweak interaction. Over the past few…
