Elementary Particle Physics

这一行动为继续研究提供了资金， 圣克鲁斯大学的一个研究小组 加州大学粒子物理研究所 Cruz. 该集团将建造和运营一个 切伦科夫环形成像探测器，用于纳入大型 探测器（SLD）在斯坦福大学直线加速器中心。 这 研究将利用仪器技术的进步 在过去的几年里， 三年 它将最终充分利用 斯坦福大学直线加速器中心的直线对撞机 探索Zo粒子物理和 这些能量中存在的其他物理过程。 特别是，该设备为SLD增加了以下能力： 将出现的粒子按类型（质量）分开， 整个能量谱的预期。 这又允许 更深入的物理分析表明， 粒子将由电子-正电子湮灭产生。 据信，没有这种能力的现代探测器 在这个能量范围的物理学中是没有竞争力的。

This action provides funds for continued research in elementary particle physics by a group at the Santa Cruz Institute of Particle Physics, University of California, Santa Cruz. The group will construct and operate major portions of a Cerenkov Ring Imaging Detector for incorporation into the Large Detector (SLD) at the Stanford Linear Accelerator Center. This research will exploit the advances in instrumental techniques in such detectors made by this and other groups over the last three years. It will culminate in the full utilization of the Stanford Linear Accelerator Center linear collider's capabilities to explore the physics of the Zo particle and of other physical processes extant at these energies. In particular, this device adds to the SLD the capability to separate emerging particles by type (mass) over virtually the entire spectrum of energies expected. This in turn allows deeper analysis of the physics which dictated that such particles would result from electron-positron annihilation. It is believed that a modern detector without such capability would not be competitive in the physics of this energy range.
