Description

The final data sets of BaBar, Belle and CDF as well as the current run of LHCb are about to significantly improve the experimental knowledge on rare $B$-decays governed by b -> s l^+l^-$. In view of this, we will present new tests of the electroweak short-distance couplings in the Standard Model and beyond, including a general set of non-standard interactions. Especially, the angular analysis of B -> K^* (->K pi) l^+l^- provides a large number of new observables which allow to efficiently disentangle short-distance (new) physics from long-distance QCD effects. The potential to test the Standard Model and specific non-standard interactions will be discussed, focusing on the high-dilepton invariant mass region, which is complementary to the low-dilepton mass region. Results of a model-independent analysis are presented, using current constraints from B -> K l^+l^- and B -> K^* l^+l^- for both regions in combination with other rare B-decays.
