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 ≈ 95 GeV, ≈ 151 GeV, ≈ 670 GeV and the (di-)di-jet excess at ≈ 1 TeV (≈ 3.6 TeV). Possible explanations in terms of new particles are briefly summarized and discussed.
