摘要
With regard to the leptonic magnetic dipole moment anomaly as well as the W -boson mass excess, we study the DFSZ axion model. Considering theoretical and experimental constraints, we show that the muon and electron g-2 anomalies can be explained within the parameter space of the model for extra Higgs bosons with mass spectra around the electroweak scale and for an almost equivalent contribution of one-and two-loop diagrams. A negative electron g-2 could be achieved by introducing heavy neutrinos. Furthermore, the W -boson mass excess can be consistently addressed within the mass range of the matter content testable at collider experiments.
