Flavour anomalies — •Johannes Albrecht — Otto-Hahn-Str. 4, 44227 Dortmund

Precision measurements of decays of heavy mesons offer a unique lab to test the Standard Model of particle physics. Heavy, virtual particles in loop processes lead to quantum corrections that are measurable in the precision tests of flavour physics. Using this strategy, hints for postulated new particles can be found. The energy range tested here extends the range reachable in direct searches by about one order of magnitude. Historically, many discoveries in particle physics have first been seen in precision measurements.

The talk will give a status of the current measurements in flavour physics with measurements of the B-factories Babar and Belle and of the LHC experiments ATLAS, CMS and LHCb. A focus of the talk will be on tensions that are currently seen in the LHCb data with respect to the Standard Model and the perspectives to clarify these in the near future.
