Abstract

Muon g-2 data can be used to study sidereal variation of anomalous muon precession rate, which is one of the important signatures of CPT and Lorentz invariance violation. The discussion in this proceeding will focus on the framework which has been used to study sidereal variation of anomalous muon precession rate in Muon g-2 Run 2 data. Also, a brief introduction will be given about the blinding framework which will be used on Run 2/3 data of Muon g-2 experiment. This blinding framework will keep the actual result of the experiment masked from the analyzer during the analysis process.
