Abstract :
The Muon g-2 Experiment at Fermilab measures the anomalous magnetic moment of the muon, aµ, with improved precision compared to the previous experiment at Brookhaven National Lab (BNL). The value of aµ from BNL currently differs from the Standard Model prediction by 3.7 standard deviations, suggesting the potential for new physics and therefore, motivating a new experiment. The Fermilab experiment follows the measurement principles of the BNL experiment, injecting a beam of positive muons into a storage ring, which focuses the beam with a combination of magnetic and electric fields. The muon anomaly relies on the measurement of the spin precession frequency, ωa about the muon momentum. The g-2 data also provides a great opportunity for setting the most stringent limits on some of the Standard Model Extension CPT LV parameters in the muon sector. The BNL g-2 experiment analyzed the spin precession frequency of the muons stored in the ring and searched for two Lorentz and CPT violating signatures. One of those signatures, the sidereal variation of ωa(t), will be discussed for the Fermilab Muon g-2 Experiment in this presentation. This talk will present the methodology and give a status update on the Run 2 analysis along with a brief overview of the experiment.
