论文摘要
一旦在ILC上观察到所有的Sleptons和Bino，就可以重建Bino对Muon异常磁偶极矩（Muon $ G-2 $）的贡献。由最近确认的MUON $ G-2 $异常动机，我们使用$ \ sqrt {s} $ = 500 GEV检查了ILC的重建精度。为此，测量Stau参数很重要。我们定量研究了ILC处的STAU的质量和混合参数的测定。此外，我们讨论了STAU研究对SUSY对MUON $ G-2 $的贡献的含义。在我们选择的基准点上，我们发现SUSY对MUON $ G-2 $的贡献可以用$ \ sim 1 \％$在ILC上确定。
Once all the sleptons as well as the Bino are observed at the ILC, the Bino contribution to the muon anomalous magnetic dipole moment (muon $g-2$) in supersymmetric (SUSY) models can be reconstructed. Motivated by the recently confirmed muon $g-2$ anomaly, we examine the reconstruction accuracy at the ILC with $\sqrt{s}$ = 500 GeV. For this purpose, measurements of stau parameters are important. We quantitatively study the determination of the mass and mixing parameters of the staus at the ILC. Furthermore, we discuss the implication of the stau study to the reconstruction of the SUSY contribution to the muon $g-2$. At the benchmark point of our choice, we find that the SUSY contribution to the muon $g-2$ can be determined with a precision of $\sim 1\%$ at the ILC.
