Abstract:
There exists a > 3s discrepancy between the experimental measurement and Standard Model
prediction of the anomalous magnetic moment for the muon. The goal of the Muon g - 2
experiment at Fermilab is to reduce the experimental uncertainty of 540 ppb to 140 ppb, which
includes improving the total systematic uncertainty by a factor of 3. A significant reduction in
the systematic uncertainty for sources associated with the dynamics of the muon beam are
needed in order to reach the achievement. For the 2018 year, Fermilab has accumulated > 2 times
the Brookhaven Muong g -2 data. The experiment is operating highly advanced tracking
detectors to measure the spatial distribution and dynamics of the muon beam. This presentation
focuses on measuring and quantifying the various systematic sources that are associated with the
dynamics of the muon beam for a portion of the Run 1 (2018) data period. As well as, using the
tracking detectors to measure an essential observable that is needed to extract the anomalous
magnetic moment for the muon.
