Anomalies in Particle Physics

Abstract

I provide a (personal) review of the current hints for physics beyond the Standard Model, called ``anomalies'', obtained both at the intensity frontier (flavour and electroweak precision observables) and in direct LHC searches. This includes the deviations from the Standard Model predictions in semi-leptonic $B$ decays, the anomalous magnetic moment of the muon, the Cabibbo Angle Anomaly, the $W$ mass as well as non-resonant di-lepton searches, the hints for new scalar particles around $\approx 95$GeV, $\approx 151$GeV, $\approx 670$GeV and the (di-)di-jet excess at $\approx 1$TeV ($\approx 3.6$TeV). Possible explanations in terms of new particles are briefly summarized and discussed.
