Description

The E989 Muon g-2 Experiment has completed its first physics run and collected a dataset roughly two times larger than the previous Brookhaven experiment. With a target precision of 140 ppb, divided equally between statistics and systematics, E989 will achieve the most precise measurement to date of the muon's anomalous magnetic moment and will thus be able to confirm or resolve the larger than 3 sigma discrepancy between theory and measurement on the muon anomaly amu = (g-2)/2. The measurement requires extracting the muon anomalous precession frequency in a highly uniform magnetic field. Systematic effects originating both from storage ring beam dynamics and detector effects must be kept under control better than 100ppb. This presentation will describe the analysis techniques as they are applied to data from the 2018 run and show blinded analysis results that demonstrate the quality of the data collected.
