Short-distance HLbL contributions to the muon anomalous magnetic moment beyond perturbation theory

Abstract The hadronic light-by-light contribution to the muon anomalous magnetic moment depends on an integration over three off-shell momenta squared ( Q i 2 $$ {Q}_i^2 $$ ) of the correlator of four electromagnetic currents and the fourth leg at zero momentum. We derive the short-distance expansio...
