Hadronic and Nuclear Structure and Dynamics

该项目的目标是利用与强相互作用的基本理论量子色动力学（QCD）严格一致的有效理论来推进对强子和轻核的理论认识。在单强子中，该项目将通过在低能状态下应用QCD的1/N展开框架，继续发展改进的重子手性有效理论方法。通过在此框架下对激发态重子的研究，本研究可用于分析包括Jefferson实验室在内的各种机构对激发态重子共振的当前实验结果，也可用于连接最近的激发态重子谱的点阵QCD计算结果。在少体物理中，研究的重点是应用手性有效理论和1/N展开联合研究核子-核子势，并可能扩展到少体电流。本项目将重点研究量子光盘在强子和核系统中的基本特性。这项研究的一项重要任务涉及汉普顿大学（Hampton University）本科生和研究生的教育和培训，这是一所历史悠久的黑人大学。PI长期参与杰斐逊实验室的理论和实验项目，为学生提供了在世界上首屈一指的实验设施之一的独特学习和研究机会。

The goals of this project are to advance the theoretical understanding of hadrons and light nuclei using effective theories that are rigorously consistent with the fundamental theory of the strong interactions, Quantum Chromodynamics (QCD). In single hadrons, the project will continue the development of improved chiral effective theoretical methods in baryons by applying in the low-energy regime a framework known as the 1/N expansion of QCD. By studying excited baryons in this framework, this research relevant for the analysis of current experimental results on baryon resonances from various facilities, including the Jefferson Laboratory, and it can also be applied to connect with recent results of Lattice QCD calculations of the excited baryon spectrum. In few-body physics, the research is focused on applying the combined chiral effective theory and 1/N expansion to study the nucleon-nucleon potential, with possible extensions to few-body currents. This project will focus on the fundamental properties of QCD as manifested in the context of hadronic and nuclear systems. An important mission of this research concerns the education and training of undergraduate and graduate students at Hampton University, one of the historically black institutions. The PI's long-standing involvement with the theoretical and experimental programs at the Jefferson Laboratory provides students with unique learning and research opportunities at one of the premier experimental facilities in the world.
