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.

这项行动将为两名教师，两名研究伙伴和四至五名学生提供资金，以继续在Fermilab的加速器设施中进行基础粒子物理学的研究。 1。一系列实验ıE594和E733的延续！研究神经元相互作用。目标包括测量电动相互作用理论中的基本参数。以及对弱相互作用的详细理解，涉及无电荷ı中性电流的变化，特别是对弱中性电流结构功能的测量！ 2。在世界上最高能量碰撞梁设施中使用D0检测器（E740）的制造和初步操作。大约150名物理学家参与了该项目，密歇根州立组的主要责任是能够从许多不太有趣的事件中选择事件的快速触发系统的设计和制造。科学兴趣是对被称为“标准模型”的电动相互作用模型进行详细而精确的测试。标准模型准确地描述了迄今为止观察到的电动相互作用，但已知有效性限于低于几百个TEV的能量。 D0实验将以比过去高的能量探测标准模型。
