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.
