This action will provide funds for two faculty, two research associates and four to five students to continue their research in elementary particle physics with accelerator facilities at Fermilab. 1. A continuation of a series of experiments ıE594 and E733! to investigate neutrino interactions. The goals include measurement of a basic parameter in the theory of electro-weak interactions ıthe Weinberg angle! and a detailed understanding of the weak interaction involving no change in electric charge ıneutral currents, in particular the measurement of weak neutral current structure functions!. 2. Collaboration in the fabrication and preliminary operation of the D0 detector (E740) to be used at the world's highest energy colliding beam facility. About 150 physicists are involved in this project, the principal responsibility of the Michigan State group is the design and fabrication of a fast trigger system capable of selecting the events for detailed analysis from the many less interesting events. The scientific interest is to make detailed and precise tests of the model of electro-weak interactions known as "the standard model". The standard model accurately describes the electro- weak interactions observed to date but is known to have validity limited to the energies below a few hundred TeV. The D0 experiment will probe the standard model at energies higher than available in the past.

这一行动将为两名教师提供资金， 研究助理和四到五名学生继续他们的 用加速器研究基本粒子物理 费米实验室的设施。 1. 一系列实验的延续<$E594和 E733！来研究中微子的相互作用 五项目标包括 电弱理论中一个基本参数的测量 相互作用温伯格角！以及详细了解 电荷不变的弱相互作用 中性电流，特别是测量弱 中性电流结构功能！ 2. 在制造和初步的合作 D 0探测器（E740）的操作将用于世界上 最高能量碰撞束设施。 大约150名物理学家 参与了这个项目，主要责任是 密歇根州立大学的设计和制造， 快速触发系统能够选择事件， 从许多不太有趣的事件中进行详细的分析。 的 科学的兴趣在于对 被称为“标准”的电-弱相互作用模型 模型”。 标准模型准确地描述了电- 迄今为止观察到的弱相互作用，但已知 有效性仅限于低于几百TeV的能量。 的 D 0实验将在更高的能量下探测标准模型 比过去更好。
