9th Plenary Workshop of the Muon g-2 Theory Initiative

The 9th Plenary Workshop of the Muon g-2 Theory Initiative hosted by University of Connecticut (UCONN) will be held on August 3-7, 2026. The aim of the workshop is to work towards reducing the total error on the Standard Model value of muon anomalous magnetic moment to the level of the Fermilab experiment (124 ppb) and resolve discrepancies between lattice QCD and data-driven approaches for the hadronic vacuum polarization contribution which dominates the total theoretical uncertainty. This series of workshops began with the formation of the theory initiative in 2017. The first plenary workshop was held near Fermilab in St. Charles, Illinois, in June 2017 and last year's was at the Irène Joliot-Curie Lab (Paris-Saclay) in Bures-sur-Yvette, France, in September 2025.
