Flavor anomalies and new physics in the beauty and charm sectors
Gudrun Hiller (TU Dortmund)

implications of the exciting hints for lepton-nonuniversality seen in ratios of rare B decays into muons and electrons at LHCb are discussed.
Iff indeed true and confirmed with more data in the future at the LHC and Belle II, this would constitute a spectacular breakdown of the standard model.
Leptoquarks provide natural explanations of the anomalies as they carry lepton and quark flavor charges and thus generically can induce nonuniversality, and lepton flavor violation. B-physics data point to masses from just around the corner, at the present search limits, to the few multi-TeV range, while viable flavor models suggest few TeV. Collider signatures are discussed. In the second part of the talk we discuss possibilities to test LNU and look for New Physics more generally with rare charm decays. While dominated by hadronic resonances we point out opportunities with Null tests to learn about flavor in the up-decotr, complementing ongoing programs with kaons and B-decays.
