A development of a compact software package for systematic error studies in muon g - 2/EDM experiment at J-PARC

The J-PARC muon g - 2/EDM experiment aims to measure the muon magnetic moment anomaly a_μ = (g - 2)/2. The target sensitivity for a_μ is a statistical uncertainty of 450×10^-9, and a_μ can be extracted by measuring the spin precession of muons (ω_a). The ω_a 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 ω_a precisely, the systematic effects on ω_a 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 ω_a
