The angle beta is the most accurately measured quantity that determines the Unitarity Triangle. In this article I review the various measurements of this angle performed by the BaBar Collaboration, and discuss their implications in the…
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…
In this article we will review recent BABAR measurements of Unitarity Triangle angle beta in B meson decays to charm and charmonium.
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…
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.
The constraints on the value of the CKM phase gamma that may be achieved by prospective measurements of sin(2 beta) and sin(2 beta + gamma) are discussed. Significant constraints require quite small errors, and may depend on assumptions…
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.
The BaBar experiment and the PEP-II accelerator at SLAC started to take data on May 26, 1999. By the time of this conference, the recorded integrated luminosity was 20 fb^{-1}, of which 8 fb^{-1} were analyzed to provide a first set of…
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…
This report summarizes the most recent progress in measuring the angle gamma (or phi_3) of the Unitarity Triangle.
The prospects for measuring the angle gamma with present day B factories are examined. A number of approaches are discussed with reference to recent preliminary measurements based on a data sample of approximately 88 million \BB pairs…
The most recent results from the B-factories on the time-dependent CP asymmetries measured in B0-decays mediated by b --> c c(bar) s quark-transitions are reviewed. The Standard Model interpretation of the results in terms of the parameter…
The BABAR detector, which operates at the SLAC PEP-II asymmetric e^+e^- collider at energies near the Y(4S) resonance, started operation on the 26th of May 1999. We present the first study of sin2beta, with samples of B0 --> J/psi K0S and…
Future neutrino oscillation measurement focus, at first priority, on the discovery of sin^2(2 theta_13) describing the coupling between solar and atmospheric oscillations. In this talk, we briefly discuss the prospects to measure sin^2(2…
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.
The time-dependent CP asymmetries in fully reconstructed B0 --> D(*)pi/rho decays (new preliminary result), and in partially reconstructed B0 --> D(*)pi decays, are measured with the BaBar detector at the PEP-II asymmetric B factory at…
Motivated by the possibility of the low value of sin2\beta in the measurements of BABAR and BELLE collaborations, a reference unitarity triangle is constructed using the unitarity of the CKM matrix and the experimental values of the well…
We review the experimental status of the angles of the Unitarity Triangle of the CKM matrix, as measured by the BABAR and Belle experiments.
The BABAR experiment has been taking data since about one year. Physics results, complementary to those described by G.Sciolla elsewhere in these Proceedings, are presented: various measurements of the neutral and charged B mesons…
