A Geometric Relation for the Muon Anomalous Magnetic Moment
Tianpeng Luo · Zenodo (CERN European Organization for Nuclear Research) · 2026
We present a compact geometric formula for the difference between the muon and electron anomalous magnetic moments. The formula contains no fitted parameters: all coefficients are derived from the combinatorial geometry of a tetrahedron. The predicted value agrees with the Fermilab final measurement at 2.2 parts per million, with a theoretical uncertainty smaller than the experimental uncertainty by a factor of 17. This suggests that the hadronic vacuum polarization contribution conventionally invoked to explain the muon g−2 discrepancy may have an equivalent geometric description.
