Understanding the nature of matter in terms of its basic building blocks, how these interact and form the elements and properties we observe, is one of the mysteries of the universe. Nuclear physics research is fundamental to our understanding of all forms of matter and how this knowledge can benefit society in the areas of national health, prosperity and welfare, and national security. This research program at The Catholic University of America is focused on studying and comparing the underlying quark-gluon structure of the basic building blocks of the atomic nucleus: its protons, neutrons, pions and kaons. This research contributes significantly to educating the future advanced STEM workforce through training of graduate, undergraduate, and high school students in state-of-the art instrumentation and machine-learning-informed software development. This research program aims at deepening the understanding of the lightest subatomic particles, the pions and kaons - their form factors, their structure functions, and their masses, and at providing measurements to validate the framework for 3D hadron imaging. The program focuses in the near and intermediate term on Jefferson Lab 12 GeV, and in the long term on the US-based Electron-Ion Collider (EIC). The experimental method uses beams of highly energetic electrons and/or photons to probe the deep inside of a hadron through exclusive and semi-inclusive scattering processes. Young scientists and students at all levels play an integral part in this project, which provides opportunities to gain experience in the design, assembly, and testing of modern subatomic particle detectors, fast signal processing electronics, and scientific data analysisThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

了解物质的性质，从其基本构建区块，它们如何相互作用和形成我们观察到的要素和特性是宇宙的奥秘之一。核物理学研究是我们对所有形式物质的理解以及这些知识如何使社会在国家健康，繁荣和福利以及国家安全领域的基础。美国天主教大学的研究计划着重于研究和比较原子核基本构建基础的基本夸克 - 杜林结构：其质子，中子，乳头和kaons。这项研究通过培训研究生，本科生和高中生，以最先进的仪器和机器学习知识的软件开发来教育未来的高级STEM劳动力。该研究计划旨在加深对最轻的亚原子颗粒，乳头和ka的理解 - 它们的形式因素，结构功能和质量，并提供测量以验证3D强子成像的框架。该计划集中在杰斐逊实验室12 GEV上的近乎和中等学期，从长远来看，该计划是基于美国的电子离子对撞机（EIC）。实验方法使用高能电子和/或光子的光束通过独家和半包含的散射过程来探测强子内部的深处。各个级别的年轻科学家和学生在该项目中起着不可或缺的作用，该项目提供了获得现代亚原子粒子探测器的设计，组装和测试经验的机会，快速信号处理电子设备以及科学数据分析，该奖项反映了NSF的法定任务，并通过使用该基金会的知识优点和广泛影响来评估NSF的法定任务。
