U.S. - Mexico Research: Search for Glueballs in High Energy Central Reactions

0104230Gutierrez美洲项目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阿卡纳大学的Marcos a . Reyes Santos博士之间的合作研究提供支持，该项目名为“寻找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物质的基本形式及其结构之间的相互作用。量子色动力学（QCD）是目前主导理论的结构和相互作用的粒子受核力。QCD的一个独特的特点是力载体，称为胶子，可以形成被称为胶球的束缚态。目前，关于这种状态的实验证据很少。这个提议将允许合作者分析现有的费米实验室数据（实验690），这些数据是用800 GeV的质子束在液氢目标上收集的。这一分析结果将有助于证实胶球在各种反应中的存在，并增加我们对基本粒子物理学的理解。

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.
