We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon $g-2$ Theory Initiative to update the Standard Model prediction.

QED and strong isospin corrections in the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon

Autor: Parato, L., Borsanyi, Sz., Fodor, Z., Guenther, J. N., Hoelbling, C., Katz, S. D., Lellouch, L., Lippert, T., Miura, K., Szabo, K. K., Stokes, F., Toth, B. C., Torok, Cs., Varnhorst, L.

Recently, the Budapest-Marseille-Wuppertal collaboration achieved sub-percent precision in the evaluation of the lowest-order hadronic vacuum polarization contribution to the muon $g_\mu-2$ (arXiv:hep-lat/2002.12347v3). At this level of precision, is

Leading hadronic contribution to the muon magnetic moment from lattice QCD

Autor: Borsanyi, Sz., Fodor, Z., Guenther, J. N., Hoelbling, C., Katz, S. D., Lellouch, L., Lippert, T., Miura, K., Parato, L., Szabo, K. K., Stokes, F., Toth, B. C., Torok, Cs., Varnhorst, L.

We compute the leading order hadronic vacuum polarization (LO-HVP) contribution to the anomalous magnetic moment of the muon, $(g_\mu-2)$, using lattice QCD. Calculations are performed with four flavors of 4-stout-improved staggered quarks, at physic
