Constraints on the two-pion contribution to hadronic vacuum polarization
At low energies hadronic vacuum polarization (HVP) is strongly dominated by two-pion intermediate states, which are responsible for about 70% of the HVP contribution to the anomalous magnetic moment of the muon, aμHVP. Lattice-QCD evaluations of the latter indicate that it might be larger than calcu...
