Computation of the anomalous magnetic moment of the muon (g-2) with lattice QCD

Abstract
Anomalous magnetic moment of the muon, aμ=(gμ−2)/2, is one of the most precisely measured quantities in particle physics and it provides a stringent test of the Standard Model. The planned improvements of the experimental precision at Fermilab and at J-PARC propel further reduction of the theoretical uncertainty of aμ. The hope is that the efforts on both sides will help resolve the current discrepancy between the experimental measurement of aμ and its theoretical prediction, and potentially gain insight into new physics. The dominant sources of the uncertainty in the theoretical prediction of aμ are the errors of the hadronic contributions. I will discuss recent progress on determination of hadronic contributions to aμ from lattice calculations.
