Description

The Fermilab Muon g-2 experiment has measured the positive muon magnetic anomaly to an unprecedented precision of 0.2 ppm, based on the data taken in the first three years. The magnetic anomaly is derived from the ratio between the muon anomalous spin precession frequency in a magnetic storage ring and the magnetic field experienced by the muon ensemble. In addition, systematic effects on the measurement of spin precession frequency due to the muon beam dynamics have to be included for an unbiased result. We considered two types of systematic effects in the analysis: i) reduction in the spin precession frequency due to electric fields and vertical motions, and ii) precession phase changes over the measurement time. In this presentation, we discuss these beam dynamics corrections applied in the Run-1 to Run-3 data analyses and provide an update since the Aug 2023 result announcement.
