Abstract

The J-PARC muon g- 2 /EDM experiment aims to measure the muon magnetic moment anomaly aμ=(g-2)/2. The target sensitivity for aμ is a statistical uncertainty of 450 × 10 - 9, and aμ can be extracted by measuring the spin precession of muons (ωa). The ωa can be extracted from the distribution of muon decay time, and the time is measured by reconstructing tracks of positrons that are decayed from the muons. To extract ωa precisely, the systematic effects on ωa should be controlled under the aforementioned sensitivity. To study systematic effects, we develop a compact simulation package, and using our developed package, we study several systematic effects and discuss the results. We discuss the implementation details of the package and studies of systematic effects on ωa.
