Description
The dispersive approach to QCD is applied to the study of the hadronic
vacuum polarization function and associated quantities. This approach
merges the intrinsically nonperturbative constraints, which originate
in the kinematic restrictions on the respective physical processes,
with corresponding perturbative input. The obtained hadronic vacuum
polarization function agrees with pertinent lattice simulation data.
The evaluated hadronic contributions to the muon anomalous magnetic
moment and to the shift of the electromagnetic fine structure constant
conform with recent assessments of these quantities.
