요약The E989 Muon g − 2 Experiment at Fermilab searches for signals of physics beyond the standard model by precisely measuring the anomalous magnetic moment of the muon (aµ) and comparing the result to the standard model prediction. The measurement of aµ can be broken into three components: measurement of the anomalous spin precession frequency of the muon (ωa), measurement of the magnetic field of the g − 2 storage ring using proton NMR, and characterization of the dynamic motion of the muon beam. Recently published results from Runs 2 and 3 of the experiment have increased the precision on the world average value of aµ by a factor of two to 0.19 parts-per-million (ppm). These results are in strong tension with a 2020 evaluation of aµ in the standard model. This thesis describes the work to analyze the remaining data (Runs 4-6) of the Muon g − 2 experiment. These datasets represent 73% of the total data collected and are expected to bring the final experimental uncertainty to ≤ 0.14 ppm. An overview of the g − 2 experiment is presented, with special attention paid to the precession frequency measurement hardware and the analysis chain through which the ωa data is processed and collated into 'physics-quality' datasets. A preliminary analysis of the Run-4 ωa data follows, which yields by itself a statistical precision of 0.19 ppm. Finally, selected systematic studies and remaining analysis work are presented and discussed.
