我们研究了通过使用 ILC 测量超粒子特性来确定超对称 (SUSY) 对 μ 子反常磁偶极矩贡献的可能性。假设贡献与 Brookhaven E821 实验结果与标准模型预测之间的当前差异一样大，我们讨论如何以及如何准确地重建 SUSY 贡献。我们将证明，在一个样本点上，质心能量为 500 GeV，积分光度为 500–1000 fb− 1 时，重建精度可达 13%。
We study the possibility to determine the supersymmetric (SUSY) contribution to the muon anomalous magnetic dipole moment by using ILC measurements of the properties of superparticles. Assuming that the contribution is as large as the current discrepancy between the result of the Brookhaven E821 experiment and the standard-model prediction, we discuss how and how accurately the SUSY contribution can be reconstructed. We will show that, in a sample point, the reconstruction can be performed with the accuracy of∼ 13% with the center-of-mass energy 500 GeV and the integrated luminosity∼ 500–1000 fb− 1.
