Investigations in Elementary Particle Physics

这一行动将为两名教员、两名研究助理和四到五名学生提供资金，以利用费米实验室的加速器设施继续他们在基本粒子物理学方面的研究。1.ıE594和E733系列实验的继续！来研究中微子相互作用。目标包括测量电弱相互作用理论中的一个基本参数，ı温伯格角！并详细了解了弱相互作用涉及的电荷不变的ı中性电流，特别是弱中性电流结构函数的测量！2.合作制造和初步操作将用于世界上能量最高的对撞束设施的D0探测器(E740)。大约150名物理学家参与了这个项目，密歇根州立大学小组的主要责任是设计和制造一个快速触发系统，能够从许多不太有趣的事件中选择事件进行详细分析。科学上的兴趣是对被称为“标准模型”的电弱相互作用模型进行详细和精确的测试。标准模型准确地描述了迄今为止观察到的电弱相互作用，但已知其有效性仅限于几百TeV以下的能量。D0实验将在比过去更高的能量下探测标准模型。

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.
