  Flavour physics plays a crucial role in the search for physics beyond the
Standard Model (SM). While $B$ physics offers many observables to look for
deviations from the SM, the highest new physics sensitivity can be obtained in
the rare kaon decays $K\to\pi\nu\bar\nu$. Of particular interest are
correlations between various flavour violating observables that allow to test
the symmetries and the operator structure of the new physics flavour sector.
New physics searches in rare meson decays are complemented by searches for new
flavour violating interactions in the production and decay of new particles at
the LHC and in dark matter phenomenology.
