However, in the attempt to address the muon anomalous magnetic moment in the context of new physics, there are often stones encountered on the way, namely constraints stemming from LFV probes.…”

We review how the muon anomalous magnetic moment (g − 2) and the quest for lepton flavor violation are intimately correlated. Indeed the decay µ → eγ is induced by the same amplitude for different choices of in-and outgoing leptons. In this work, we try to address some intriguing questions such as:Which hierarchy in the charged lepton sector one should have in order to reconcile possible signals coming simultaneously from g − 2 and lepton flavor violation?What can we learn if the g − 2 anomaly is confirmed by the upcoming flagship experiments at FERMILAB and J-PARC, and no signal is seen in the decay µ → eγ in the foreseeable future? On the other hand, if the µ → eγ decay is seen in the upcoming years, do we need to necessarily observe a signal also in g − 2?.In this attempt, we generally study the correlation between these observables in a detailed analysis of simplified models. We derive master integrals and

“…As far as accelerator-based experiments are concerned-aside from some much-discussed discrepancies such as the value of the muon (g − 2) [33]-the SM does an excellent job of explaining the wide variety of elementary particle phenomena. The main objection to the idea that the SM is a complete explanation comes from theory.…”
