        The leading order hadronic contribution to the
             anomalous magnetic moment of the muon

The anomalous magnetic moment of the muon is one of the most precisely 
measured physical quantities. Comparing its experimental value to the 
theoretical prediction of the Standard Model (SM) provides a stringent 
test of SM, and a possible disagreement can indicate new physics. The 
dominant source of uncertainty in the recent theoretical determinations 
is the hadronic loop corrections arising from the hadronic vacuum 
polarization (HVP). Due to the large coupling constant of the strong 
interaction at low energies, the HVP contribution is only accessible by 
non-perturbative methods. In the talk I will discuss how the hadronic 
contributions can be addressed non-perturbatively using lattice QCD, 
then I will present recent results on the leading order hadronic 
contribution obtained by the Budapest-Marseille-Wuppertal collaboration.
