Anomalies in B decays

25.04.2018 11:15 – 12:15

Flavour-changing neutral currents (FCNCs) only proceed via loop level in the Standard Model and therefore offer an excellent probe for new physics. In the last years, several measurements of rare B decays proceeding via FCNCs have shown deviations from the Standard Model predictions.

After an introduction to the LHCb detector I will talk about the most important measurements of rare B decays and about the comparison with theoretical predictions. I will highlight the results from angular analyses and tests of lepton flavor universality in b -> s l l transitions from LHCb and other experiments, and the possible connection of all anomalies, including the puzzling deviations from the Standard Model seen in semileptonic B decays.
