0104230GutierrezThis Americas Program award will provide support for cooperative research between Dr. Gaston Gutierrez of Fermi National Accelerator Laboratory and Dr. Marcos A. Reyes Santos of the Universidad Michoacana in Morelia, Mexico, on a project entitled "Search for Glueballs in High Energy Central Reactions."A fundamental objective of all particle physics research is to understand the interactions of the basic forms of matter and their structure. Quantum Chromodynamics (QCD) is currently the leading theory governing the structure and interactions of particles subject to the nuclear force. A unique feature of QCD is that the force carrier, called gluons, may form bound states known as glueballs. At present, there is little experimental evidence about such states. This proposal will allow the collaborators to analyze existing Fermilab data (Experiment 690), which was collected using an 800 GeV proton beam on a liquid hydrogen target. The results of this analysis will serve to confirm the existence of glueballs in various reactions and increase our understanding of elementary particle physics.

0104230Gutierrez 该美洲计划奖将为费米国家加速器实验室的 Gaston Gutierrez 博士和墨西哥莫雷利亚米却肯大学的 Marcos A. Reyes Santos 博士之间的合作研究提供支持，该项目名为“搜索高能中心反应中的胶球”。所有粒子物理研究的一个基本目标是了解粒子基本形式的相互作用。 物质及其结构。 量子色动力学（QCD）是目前控制受核力影响的粒子结构和相互作用的领先理论。 QCD 的一个独特特征是，称为胶子的力载体可以形成称为胶球的束缚态。 目前，关于这种状态的实验证据很少。 该提案将使合作者能够分析现有的费米实验室数据（实验 690），这些数据是使用 800 GeV 质子束在液氢靶上收集的。 这一分析的结果将有助于证实各种反应中胶球的存在，并增加我们对基本粒子物理学的理解。
