The updated SM prediction for the muon anomalous magnetic moment is 116592033(62)×10^{-11}, showing no tension with the experimental average of 38(63)×10^{-11}.
Hadronic form factors violate QCD dispersion relations due to incomplete time-like spectral data above the last known resonance, which radial Regge trajectories can fill as a minimal ansatz, shown for the pion form factor.
A hadronic approach based on dispersion relations and meson dominance achieves a successful description of lattice QCD data for gravitational form factors of pions and nucleons.
