CKM angles from non-leptonic B decays using SU(3) flavour symmetry

PS03 CP Violation


We discuss the determination of the CKM angles γ and α using recent data from non-leptonic B decays together with flavour symmetries. Penguin effects are controlled by means of the CP-averaged branching ratio B d π± K. The information from \({\cal A}_{CP}(B_d \to J/\Psi K_S)\) (two solutions for φ d ), R b and γ allow us to determine β, even in presence of New Physics not affecting Δ B=1 amplitudes. In this context we address the question of to what extent there is still space for New Physics.
