A call for new physics: the muon anomalous magnetic moment and lepton flavor violation
M Lindner, M Platscher, FS Queiroz - Physics Reports, 2018 - Elsevier
We review how the muon anomalous magnetic moment (g− 2) and the quest for lepton flavor
violation are intimately correlated. Indeed the decay μ→ e γ is induced by the same …
