Measurement of the CKM Angles at BaBar and Belle
The primary goal of the BaBar and Belle experiments is to overconstrain the CKM Unitarity Triangle. Measurements of the angles of this triangle, known as β, α, and γ (or φ1, φ2, and φ3) give insight into the Standard Model description of CP violation in the quark sector. BaBar and Belle have recorded almost 1 ab−1 combined, and have measured β to high precision. Measurements of α and γ are less...
متن کاملMeasurement of the CKM angle γ at LHCb
The precise measurement of the CKM unitarity triangle angle γ is a key goal of the LHCb physics programme. The uncertainty on γ, the currently least-well known of the three angles, will be reduced dramatically. Complementary measurements will be made in tree-level processes, and modes where loop diagrams play an important role. The tree-level measurements will cover time-integrated as well as t...
متن کاملAngles of the Ckm Unitarity Triangle Measured at Belle
The Belle experiment has used several methods to measure or constrain the angles φ 1 , φ 2 , and φ 3 (or β, α, and γ) of the CKM unitarity triangle.

We present results from an analysis of B → ρ+ρ− using 316 fb−1 of Υ (4S) → BB decays observed with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure the B → ρ+ρ− branching fraction, longitudinal polarization fraction fL, and the CP -violating parameters Slong and Clong: B(B → ρρ) = (23.5 ± 2.2(stat) ± 4.1(syst))×10, fL = 0.977 ± 0.024(stat) −0.013(syst), Slong = −...
