A Program of Medium Energy Nuclear Physics

美国国家科学基金会支持的中能量核物理项目将允许伊利诺伊大学厄巴纳-香槟分校的核物理小组继续领导并为国际核物理研究中的高影响力实验做出贡献。本研究计划有两大主题，即核子和原子核的结构和相互作用，以及基本对称性和标准模型。在这个项目中，实验所追求的物理学将有助于回答这样的问题：质子是如何形成的？以及当前的粒子物理标准模型是否正确？具体活动包括以下主要的、已建立的国际实验：G0、HERMES、PHENIX、MuLan和MuCap。此外，该小组正在帮助开发一个新的μ子g-2实验和对中子电偶极矩的敏感搜索。除了直接的物理研究成果外，该小组已经超越了实验室，为教育和推广做出了重大贡献，并将继续这样做。研究项目对培养大量博士后、研究生和本科生做出了重大贡献。

The NSF-supported Program of Medium Energy Nuclear Physics will allow the nuclear physics group at the University of Illinois at Urbana-Champaign to continue to lead and contribute to high-impact experiments in international nuclear physics research. The research program fea-tures two major themes, namely 1) the structure and interactions of nucleons and nuclei and 2) fundamental symmetries and the standard model. The physics pursued by experiments in this program will help answer questions such as, How is the proton built? and Is the current parti-cle physics standard model correct? Specific activities include the following major, established international experiments: G0, HERMES, PHENIX, MuLan, and MuCap. Additionally, the group is helping to develop a new muon g-2 experiment and a sensitive search for a neutron elec-tric dipole moment. In addition to direct physics research outcomes, the group has reached be-yond the laboratory to make significant contributions to education and outreach and will con-tinue to do so. Research projects contribute substantially to the education of a large number of postdocs, graduate, and undergraduate students.
