Extensible Computational Services for Discovery of New Particles

物质的起源是自然界最大的谜题之一。尽管可见成分只是宇宙质量/能量平衡的一小部分，但将夸克和胶子永久限制在原子核中的强大力量仍然是个谜。对禁闭现象的理解是物理学的基本问题之一。质子、中子和其他强子是禁闭所允许的夸克和胶子的束缚态。该项目将继续研究单个强子及其相互作用，并有望为了解这一基本现象提供一个独特的窗口。在这一过程中，该项目将使光谱分析的最佳实践跨越一系列即将进行的实验，特别是在杰斐逊实验室。教育活动是这一努力的组成部分。学生将有大量的培训机会，并将获得计算和分析技能，这将为他们未来在行业或学术界的职业生涯提供良好的服务。杰斐逊实验室的研究人员将主持一系列充满活力的夏季本科生研究经验，包括计算机科学和粒子物理项目。粒子加速器和探测技术的发展导致了在世界各地蓬勃发展的新一代强子物理实验。一组重要的实验研究了强子光谱学，强子的存在和性质。这些设施的新实验产生了复杂的数据集，这需要在分析方面达到前所未有的全新水平的复杂程度。该项目的目标是开发新的理论工具和基本的计算服务，用于分析目前和未来强子光谱学实验中的大型统计数据集，目的是寻找新的强子，特别是所谓的杂化和胶球，预计它们将带有限制现象的一些独特特征。强相互作用基本理论的独特特征也使其成为构建超越基本相互作用标准模型的理论的一个有吸引力的模板。这个项目将使这项工作成为可能。

The origin of matter is one of the great puzzles of nature. Even though the visible component is only a small part of the mass/energy balance of the universe the strong force that permanently confines quarks and gluons to atomic nuclei remains mysterious. Understanding of the phenomenon of confinement is one of the fundamental questions in physics. Protons, neutrons and other hadrons are the bound states of quarks and gluons allowed by confinement. This project will pursue studies of individual hadrons and their interaction and is expected to offer a unique window into this fundamental phenomenon. In the process, this project will enable best practice spectroscopy analysis across a broad range of forthcoming experiments, particularly at the Jefferson Laboratory. Education activities are an integral part of this effort. Students will have ample training opportunities and will acquire computational and analytical skills that will serve them well in their future careers in the industry or academia. A vibrant set of summer undergraduate research experiences will be hosted by the investigators at the Jefferson Laboratory with both computer science and particle physics projects.Developments in particle accelerators and detection techniques have led to a new generation of experiments in hadron physics that are flourishing around the world. An important set of experiments studies hadron spectroscopy, what hadrons exist and with what properties. The new experiments at these facilities generate complicated data sets, which demand a qualitatively new level of sophistication in analysis never achieved before. The objective of the project is to develop new theoretical tools and underlying computational services for analysis of large statistics data sets from current and future experiments in hadron spectroscopy with the goal to search for new hadrons, in particular the so called, hybrids and glueballs, which are expected to carry some unique signatures of the confinement phenomenon. The unique features of the underlying theory of strong interactions also make it an attractive template for constructing theories beyond the Standard Model of fundamental interaction. This project will enable such work.
