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 $450 \times 10^{-9}$, 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 which 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 results. We discuss the package details and studies of systematic effects on $ω_a$ based on our package.
