Abstract
The Muon g-2 Experiment at Fermilab (E989) aims to measure the muon magnetic anomaly ($a_{\mu}$) with a final accuracy of 140 parts per billion (ppb). The first result on the Run-1 dataset was unveiled on April 7, 2021, showing a very good agreement with the previous result from the Brookhaven National Laboratory (BNL) experiment, with a slightly better uncertainty. The corresponding experimental average increases the significance of the discrepancy between the measured and Standard Model predicted $a_{\mu}$ to 4.2 $\sigma$. Four different beam dynamics corrections must be applied to obtain the final value of the anomalous precession frequency. In the following contribution, this high precision measurement is presented, focusing on the beam dynamics corrections to $\omega_a$.
