Electromagnetic suppression of the decay mu --> e+gamma
Due to large QED anomalous dimensions of the electric and magnetic dipole operators, the rate of the rare muon decay mu --> e+gamma is suppressed by the factor [ 1- 8 alpha/pi ln(Lambda/m_mu) ], independent of the physics responsible for the lepton-flavor violation, except for the scale Lambda at...
