چکیده
The time-dependent CP asymmetries in fully reconstructed B0→D(∗)±π∓/ρ∓ decays (new preliminary result), and in partially reconstructed B0→D(∗)±π∓ decays, are measured with the BABAR detector at the PEP-II asymmetric B factory at SLAC, using 232 million Υ (4S) → BB decays. We combine the above results and, using other measurements and theoretical assumptions, we interpret them in terms of the angles of the unitarity triangle describing the CabibboKobayashi-Maskawa matrix. We find |sin(2β + γ)| > 0.64(0.42) at 68%(90%) confidence level using a frequentistic approach and |2β + γ|=(90±43)o using a Bayesian approach.

CP 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 کاملAsymmetry A ψK S , sin 2 β , the Sign of ∆ M B and the Physics Beyond the Standard Model
We demonstrate that the sign of the B−B̄ mass difference ∆MB is irrelevant for the extraction of the angle β = φ1 of the unitarity triangle from the CP asymmetry AψKS . Only the weak phase in the mixing amplitude M12 matters. Consequently the extraction of sin 2β done by BaBar and Belle can only be affected by new weak phases in M12 in the extensions of the SM and possibly but unlikely by new ph...

متن کاملA Lower Bound on sin 2β from Minimal Flavour Violation
We point out that there exists an absolute lower bound on sin 2β in all models with minimal flavour violation (MFV), that do not have any new operators beyond those present in the Standard Model and in which all flavour changing transitions are governed by the CKMmatrix with no new phases beyond the KM phase. This bound depends only on |Vcb|, |Vub/Vcb| and the hadronic parameters B̂K , FBd √ B̂d ...
متن کاملMeasurements of sin 2 β at B A B AR with charmonium and penguin decays
Measurements of sin 2β at BABAR with charmonium and penguin decays. Abstract This article summarises measurements of time-dependent CP asymmetries in decays of neutral B mesons to charmonium, open-charm and gluonic penguin-dominated charmless final states. Unless otherwise stated, these measurements are based on a sample of approximately 230 million Υ (4S)→ BB decays collected by the BABAR dete...
