Abstract
The discrepancy between theoretical and experimental values for the anomalous magnetic moment of the muon, aμ, is one of the most important indications for new physics. The Muon g−2 experiment at Fermi National Accelerator Laboratory (FNAL) aims to measure the anomalous magnetic moment of the muon to a record precision of 140 parts per billion using data taken over six years from 2018 to 2023. The first result which was based on the Run-1 data comprises 6% of the total statistics. The Runs 2 and 3 data were collected in 2019-2020 and published in 2023. These results measured the positive muon anomalous magnetic moment to 0.20 parts per million, which is the world’s most precise measurement of the anomalous magnetic moment of the muon.
Muon g − 2 data can be used to search for a sidereal (and sidereal harmonics) variation of the anomalous muon spin precession frequency, which is one of the important potential signatures of Charge, Parity, Time Reversal Symmetry, and Lorentz Invariance Violation in the muon sector. This analysis focuses on the framework that has been used to study the variation of this precession frequency at the sidereal frequency and its first five harmonics using FNAL muon g − 2 data. It includes a detailed description of systematic uncertainty studies, and the blinding framework which has been used on the entire Run 2 and Run 3 dataset.
