dc.descriptionDue 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 which it occurs. For Lambda = 100 -- 1000 GeV, the resulting decrease of the rate amounts to about 12 -- 17 %.
