Measurement 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 کاملMeasurement of the CKM Angle α Using B 0 →
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 = −...
