Hadronic corrections to muon anomalous magnetic moment within the instanton liquid model

Abstract

The current status of the muon anomalous magnetic moment problem is briefly presented. The corrections to muon anomaly coming from the effects of hadronic vacuum polarization, Z*\gamma\gamma* effective vertex and light-by-light scattering are estimated within the instanton model of QCD vacuum.
