Journal Article
Radiative lepton mass and muon g − 2 with suppressed lepton flavor and CP violations
2021
Overview
A
bstract
The recent experimental status, including the confirmation of the muon
g −
2 anomaly at Fermilab, indicates a Beyond Standard Model (BSM) satisfying the following properties: 1) it enhances the
g −
2 2) suppresses flavor violations, such as
μ → eγ
, 3) suppresses CP violations, such as the electron electric dipole moment (EDM). In this letter, I show that the eigenbasis of the mass matrix and higher dimensional photon operators can be automatically aligned if the masses of heavy leptons are generated radiatively together with the
g −
2. As a result, the muon
g −
2 is enhanced but the EDM of the electron and
μ → eγ
rate are naturally suppressed. Phenomenology and applications of the mechanism to the B-physics anomalies are argued.
