Description
The anomalous magnetic moment of the muon is a key precision observable in particle physics and serves as a sensitive probe for physics beyond the Standard Model. A seeming experimental deviation from its predicted Standard Model value has motivated a flurry of theoretical and experimental work on the subject in the past decade.

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 measure-ments 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 close future.
