Investigations in Elementary Particle Physics

这项行动将为两名教员、两名研究助理和四到五名学生提供资金，以继续他们在费米实验室的加速器设备上进行基本粒子物理学的研究。一系列实验的延续ıE594和E733！研究中微子的相互作用。目标包括测量电-弱相互作用理论中的一个基本参数ıthe温伯格角！并详细了解了不涉及电荷变化ıneutral电流的弱相互作用，特别是测量了弱中性电流的结构功能！2. 在D0探测器（E740）的制造和初步操作方面的合作，该探测器将用于世界上最高能量的碰撞束设施。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。科学界的兴趣在于对被称为“标准模型”的电-弱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测到的电弱相互作用，但已知其有效性仅限于低于几百TeV的能量。D0实验将以比过去更高的能量探测标准模型。

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.
