Abstract

The recent experimental status, including the confirmation of the muon g2g-2 anomaly at Fermilab, indicates a Beyond Standard Model (BSM) satisfying the following properties: 1) it enhances the g2g-2 2) suppresses flavor violations, such as μeγ\mu \to e \gamma, 3) suppresses CP violations, such as the electron electric dipole moment (EDM). In this letter, I show that if the masses of heavy leptons are generated radiatively, the eigenbasis of the mass matrix and higher dimensional photon operators can be automatically aligned. As a result, the muon g2g-2 is enhanced but the EDM of the electron and μeγ\mu \to e \gamma rate are suppressed. Phenomenology and applications of the mechanism to the B-physics anomalies are argued.
