| 摘 要： | 布鲁克海文的Ｅ８２１是一个新的测量μ介子反常磁矩的高精度实验．要求达到的精度为０．３５ｐｐｍ，比ＣＥＲＮ的实验精度高２０倍．精度的提高将提供对ＴｅＶ质量范围虚粒子的敏感性及为发现标准模型以外新物理打开一个重要的窗口．同时Ｅ８２１的超高精度在技术及物理上提出了不寻常的挑战.A new measurement of the muon anomalous magnetic moment (BNL E821) aims to obtain a precision of 0.35 ppm which is 20 times higher than that of CERN measurement. This increase in precision will provied a sensitivity to virtual particles into the TeV mass range and open a substantial window for the discovery of new physics beyond the standard model. Meanwhile the ultahigh precision aimed for in the BNL experiment gives unusual challenges in physics and in technology.

| Abstract: | A new measurement of the muon anomalous magnetic moment (BNL E821) aims to obtain a precision of 0.35 ppm which is 20 times higher than that of CERN measurement. This increase in precision will provied a sensitivity to virtual particles into the TeV mass range and open a substantial window for the discovery of new physics beyond the standard model. Meanwhile the ultahigh precision aimed for in the BNL experiment gives unusual challenges in physics and in technology. |
