This award is a continuation of a program of research in elementary particle physics at the University of Chicago which consists of three teams, each of which is playing a leading role in one of the premier experiments in particle physics on a world- wide scale: (1) the CDF experiment at the 1.8 Tev proton- antiproton collider at Fermilab in Batavia, Illinois; (2) the OPAL experiment that is one of the four detectors at LEP, a large electron-positron collider at CERN in Geneva, Switzerland, and (3) the KTEV experiment, which is being constructed for the new K meson beam in the fixed target program at Fermilab. The major goal of CDF is to find the top quark, the last and heaviest of the six components of hadronic matter in the Standard Model. Opal is investigating the Z , the neutral intermediate vector boson that, along with the photon, is central to the unification of the electromagnetic forces and the force governing nuclear beta decay. KTEV is the next step in a program that is attempting to understand the origin of CP symmetry violation which in turn is thought to be the key to understanding the asymmetry between matter and antimatter in the universe - a necessary prerequisite to our existence. The grant will support, including the Principal Investigator, Professor Frank Merritt, 9 faculty members, 3 senior researchers, 9 postdoctoral research associates, 17 graduate students and a majority of the technical staff at the Enrico Fermi Institute.

该奖项是芝加哥大学基本粒子物理研究项目的延续，该项目由三个团队组成，每个团队都在全球范围内粒子物理最重要的实验之一中发挥着主导作用：（1）伊利诺伊州巴达维亚费米实验室 1.8 Tev 质子-反质子对撞机上的 CDF 实验； (2) OPAL 实验是 LEP 的四个探测器之一，LEP 是瑞士日内瓦 CERN 的大型正负电子对撞机；(3) KTEV 实验，该实验是为费米实验室固定目标计划中的新 K 介子束而建造的。 CDF 的主要目标是找到顶夸克，它是标准模型中强子物质的六个组成部分中最后一个也是最重的一个。 Opal 正在研究 Z ，即中性中间矢量玻色子，它与光子一起，对于电磁力和控制核 β 衰变的力的统一至关重要。 KTEV 是一个计划的下一步，该计划试图了解 CP 对称性破坏的起源，而这反过来又被认为是理解宇宙中物质和反物质之间不对称性的关键——这是我们存在的必要先决条件。 这笔赠款将支持恩里科费米研究所的首席研究员 Frank Merritt 教授、9 名教员、3 名高级研究员、9 名博士后研究员、17 名研究生和大部分技术人员。
