摘要
本文介绍了在升级至 12 GeV 的杰斐逊实验室（Jefferson Lab）进行的 MOLLER（轻子 - 轻子电弱反应测量）实验的物理依据与实验概况。2007 年核科学咨询委员会（NSAC）长期规划中基础对称性子领域的一个亮点是 SLAC E158 实验对极化电子 - 电子（M{\o}ller）散射中宇称破坏不对称性 的测量。拟议的 MOLLER 实验将该结果提高了五倍，有望在未来十年内提供低能或高能下最精确的弱混合角测量值。这一新结果将对电磁振幅与来自标准模型之外尚未发现的动力学的新中性流振幅之间的干涉敏感，后者强度可低至 。由此产生的发现能力在未来十年内任何测量味守恒和 CP 守恒过程的拟议实验中都是无与伦比的，并为 MeV 和多 TeV 能标的新物理提供了一个独特的窗口，是对大型强子对撞机（LHC）等高能对撞机直接搜索的补充。该实验利用了杰斐逊实验室升级后的电子束能量、亮度和稳定性所提供的独特机遇，以及社区在最近一轮成功完成的宇称破坏电子散射实验后积累的丰富经验。
