Description
The hadronic contributions to the anomalous magnetic moment of the muon are an interesting challenge for lattice QCD calculations, especially given a persistent discrepancy between theory and experiment. We have calculated the leading order hadronic contribution for pion masses from 270 MeV to 600 MeV using two flavors of dynamical twisted-mass fermions. We have examined the finite-size dependence with spatial volumes ranging from (1.6 fm)^3 to (2.7 fm)^3 and we have studied lattice artifacts with lattice spacings of 0.086 fm and 0.067 fm.
