| 摘要: |
The most recent measurement of the fine structure constant leads to a 2.4 sigma deviation in the electron anomalous magnetic moment g(e) - 2, while the muon anomalous magnetic moment g(mu) - 2 has a long-standing 3.7 sigma deviation in the opposite direction. We show that these deviations can be explained in a three-loop neutrino mass model based on an E-6 Grand Unified Theory. We also study the impact such a model can have on the anomalous events observed by the ANITA experiment and find an insufficient enhancement of the event rate. |
