sin(2β): Status and Prospects
نویسنده
چکیده
An overview of the observation of CP violation in the neutral B system, and the measurements of the CP-violating asymmetry sin2β with B → charmonium K0 S ,L events, performed by the BABAR and Belle experiments at the SLAC and KEK B factories is given. In addition, the measurements of sin2β with several other modes are described, including B → φK0 S , which, as the leading contribution is from a loop diagram, could be sensitive to physics beyond the Standard Model.

Testing the standard model and schemes for quark mass matrices with CP asymmetries in B decays.
The values of sin 2α and sin 2β, where α and β are angles of the unitarity triangle, will be readily measured in a B factory (and maybe also in hadron colliders). We study the standard model constraints in the sin 2α − sin 2β plane. We use the results from recent analyses of fB and τb|Vcb| which take into account heavy quark symmetry considerations. We find sin 2β ≥ 0.15 and most likely sin 2β ...
متن کاملSe p 19 96 Heavy Flavour Decays - Introduction and Summary
We review some selected topics in the decays of heavy flavours, beauty and charm, which are of principal interest at HERA-B and HERA. The topics in B physics include: an update on the quark mixing matrix and CP violating phases, issues bearing on an improved resolution on the CP-violating phase ∆(sin 2β), prospects of measuring radiative and semileptonic rare B decays, the B 0 s-B 0 s mixing ra...
متن کاملCP Violation in B Decays and the CKM Matrix
Results by the BaBar and Belle experiments of the measurements sin 2α, sin 2β and sin(2β + γ) along with the CKM matrix elements Vcb and Vub are presented. The BaBar and Belle experiments b → scc̄ results for sin 2β are in good agreement with each other, comfortably establishing CP violation within B decays. However, there is a 3.5 standard deviation between this result and sin 2β measured by th...
متن کاملFlavor Tagging and Cp-violation Measurements at the Tevatron
The CDF collaboration has adapted several heavy flavor tagging techniques and employed them in analyses of time-dependent flavor asymmetries using data from the Tevatron Run I. The tagging algorithms were calibrated using low-Pt inclusive lepton and dilepton trigger data samples. The tagging techniques were applied to a sample of ∼ 400 B d /Bd → J/ψK 0 s decays and were used to measure the CP v...
متن کاملThe measurement of sin(2β)
Since the first observation in 1964, CP violation remains one of the most elusive aspects of the standard model. The CDF collaboration has reported the first evidence of CP violation in the B system using the world’s largest sample of B → J/ψK S decays. The direct measurement of sin(2β)=0.79 −0.44 (combined statistical and systematic error) agrees with the standard model predictions. New data c...
