Abstract

Rare flavour changing neutral current decays of strange, charm and beauty hadrons have been instrumental in building up a picture of flavour in the Standard Model. Increasingly precise measurements of these decays allow to search for deviations from predictions of the Standard Model that would be associated to contributions from new particles that might arise in extensions of the Standard Model. In this summary, an overview of recent experimental results and theoretical predictions is given. The new physics sensitivity and prospects for the different observables is also addressed.
