ArXe Prediction: Tau Anomalous Magnetic Moment from 8/π Factor Executive Summary We derive a prediction for the tau lepton’s anomalous magnetic moment (a_τ) using ArXe theory’s geometric structure. The key insight is that the factor 8/π ≈ 2.546, which appears in the tau’s mass generation (m_τ/m_μ ratio), should also manifest in its magnetic moment through radiative corrections. Central Prediction: a_τ…
