Explaining the Flavour Anomalies with Leptoquarks

Several experiments observed deviations from the Standard Model (SM) in the flavour sector: LHCb found a 5 $σ$ discrepancy compared to the SM in $b → sμ^+ μ^−$ transitions (including hints for lepton flavour universality violation (LFUV) in $R(K)$ and $R(K*))$. In addition BELLE, BABAR and LHCb foun...

description Several experiments observed deviations from the Standard Model (SM) in the flavour sector: LHCb found a 5 $σ$ discrepancy compared to the SM in $b → sμ^+ μ^−$ transitions (including hints for lepton flavour universality violation (LFUV) in $R(K)$ and $R(K*))$. In addition BELLE, BABAR and LHCb founds hints for LFUV in $b →cτ\nu$ transitions at the 4 $σ$ level. In addition, there is the long-standing discrepancy in the anomalous magnetic moment of the muon with a significance of more than 3 $σ$. All these anomalies are related to muons and taus, while the corresponding electron channels seem to be SM like. Interestingly, leptoquarks provide a common solutions to all these hints for LFUV which I discuss in these proceedings.
