I will describe recent progress in approaching the calculation of the hadronic light-by-light contribution to (g-2)_mu with dispersive methods. I will first discuss general properties of the four-point function of the electromagnetic current in QCD, its Lorentz decomposition and dispersive representation. For what concerns the pseudoscalar pole contributions, I will give an overview of the...

Recent studies of the hadronic vacuum polarization and hadronic light-by-light scattering contributions to the muon anomalous magnetic moment (g-2) are reviewed. Attention is paid to systematic errors arising from finite volume and non-zero lattice spacing, among others. The problem of disconnected quark loop diagrams is also discussed.

We discuss the current status of the theoretical prediction for the muon anomalous magnetic moment in Standard Model. Recent developments in estimation of hadronic vacuum polarization are described based on measurements of e+ e− → hadrons cross section in Novosibirsk and Beijing as well as those with ISR at KLOE, BaBar and Belle. We also briefly review expectations for experiment and theory in...
