Title: First Results From The Muon g-2 Experiment

Abstract: 
The Muon g-2 Experiment at Fermilab recently reported its first result for the measured value of the anomalous magnetic moment of the muon, which confirms the longstanding discrepancy with the theoretical Standard Model (SM) prediction. With this new measurement (which boats major improvements on its predecessor experiment), this deviation now stands at a significance of 4.2 standard deviations, providing a strong indication of the existence of new physics beyond the SM. As part of this result, the SM prediction of the Muon g-2, in particular the hadronic contributions, have been re-evaluated in detail by the Muon g-2 Theory Initiative and has resulted in the first community-approved consensus value of this quantity to be compared with experiment. As a member of both the Muon g-2 Experiment and Muon g-2 Theory Initiative, I will describe the updates and status of both the measurement and SM calculation that have led to this result, and discuss plans for the future of the Muon g-2.
