Abstract

© 2003, Springer-Verlag, Società Italiana di Fisica. 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 Bd → π±K∓. The information from ACP(Bd → J/ΨKS) (two solutions for φd), Rb and γ allow us to determine β, even in presence of New Physics not affecting ΔB=1 amplitudes. In this context we address the question of to what extent there is still space for New Physics. PACS: 13.25Hw Hadronic decays of mesons – 11.30Er CP violation.
