Extracting the Bs - anti-Bs mixing angle from B--> VV decays and comments on the puzzling B--> K* l+l- decay
arXiv:0807.2579 · doi:10.1016/j.nuclphysbps.2008.10.031
Abstract
Three different strategies to extract the weak mixing phase phi_s of the Bs system using B--> VV decays (Bs--> K* anti-K*, Bs--> phi anti-K* and Bs--> phi phi) 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.
