We consider possible beyond-the-Standard-Model (BSM) effects that can accommodate both the long-standing tension in the anomalous magnetic moment of the muon, aμ=(g−2)μ/2, as well as the emerging 2.5σ deviation in its electron counterpart, ae=(g−2)e/2. After performing an EFT analysis, we consider BSM physics realized above the electroweak scale and find that a simultaneous explanation becomes...

A permanent EDM of an elementary particle violates parity (P) and time reversal (T) symmetry, and assuming CPT invariance, T violation implies CP violation. EDM predicted by the Standard Model (SM) are far too small to be detected with current experimental techniques, therefore, any observation of non-zero EDMs would strongly indicate the existence of physics beyond the SM (BSM).
The muon is...
