Hadronic vacuum polarization for the muon g – 2 from lattice QCD: Precision results from the Fermilab Lattice, HPQCD, and MILC collaborations

Oral-In-person

Abstract

An ongoing project of the Fermilab Lattice, HPQCD, and MILC collaborations is the precision calculation of the hadronic vacuum polarization (HVP) contribution to the anomalous magnetic moment of the muon. In this talk, we discuss results for all contributions to the leading-order HVP, including the dominant isospin-symmetric quantities (connected light-, strange-, and charm-quark contributions and disconnected light and strange diagrams) and their corrections including strong isospin breaking and QED. Results for next-to-leading order HVP are also discussed. All calculations are performed on highly-improved staggered-quark (HISQ) ensembles with 2+1+1 flavors and a physical pion mass. A companion talk by Michael Lynch will discuss long-distance statistical and systematic effects.
