摘要：

We provide a comprehensive model-independent analysis of rare decays involving the b -> s transition to put constraints on dimension-six Delta F = 1 effective operators. The constraints are derived from all the available up-to-date experimental data from the B-factories, CDF and LHCb. The implications and future prospects for observables in b -> sl(+)l(-) and b -> sv (v) over bar transitions in view of improved measurements are also investigated. The present work updates and generalises previous studies providing, at the same time, a useful tool to test the flavour structure of any theory beyond the SM.
