The LHCb experiment at CERN’s Large Hadron Collider is one of the most sensitive instruments for seeking sources of physics beyond the Standard Model. Rare decays of heavy flavour are heavily suppressed in the Standard Model, and new particles can give sizeable contributions to these processes. Their precise study therefore allows for sensitive tests of lepton-flavour universality, as well as detailed measurements of angular observables.
Of particular interest are rare b—> sll decays, which are readily accessible at the LHCb experiment. Recent results from LHCb on rare b—> sll decays are discussed.
