Abstract

Three different strategies to extract the weak mixing phase φ{symbol}s of the Bs system using B → V V decays (Bs → K* 0 over(K, -)* 0, Bs → φ{symbol} over(K, -)* 0 and Bs → φ{symbol} φ{symbol}) are discussed. Those penguin-mediated decays are computed in the framework of a new combined QCD-Factorisation/Flavour Symmetry Method. Also some comments on the recent interesting results found by Babar concerning the decay B → K* l+ l- are included. © 2008 Elsevier B.V. All rights reserved.
