The Muon g-2 Experiment at Fermilab has recently measured the muon magnetic anomaly with 460 parts per billion precision. This result is consistent with the measurement from the previous BNL experiment, and the combined Fermilab-BNL value deviates from the most recent Standard Model calculation provided by the Muon g-2 Theory Initiative at the level of 4.2 standard deviations. The muon anomaly is determined by measuring muon spin precession, relative to the muon momentum, inside of a ~7m-radius storage ring which has a very uniform and precisely measured magnetic field. It is necessary to quantify and correct for the effects from storage ring beam and spin dynamics, so as to achieve the required experimental precision for probing the Standard Model. This talk will give an overview of the beam dynamics corrections that are required for the Fermilab measurement.
