This research program is centered on experiments addressing fundamental issues of nuclear physics. An experiment is being designed to search for a non-zero electric dipole moment of the neutron, whose possible existence is of fundamental interest and would significantly challenge the theoretical extensions of the Standard Model of elementary particle physics. Another experiment under analysis measured second order effects in electron-proton scattering to address a present puzzle on the proton structure data. And there are on-going experiments with cold neutrons measuring the strength of the weak interaction among quarks to be followed by precise new measurements of the parameters governing the neutron decay, which can have an important impact on our understanding of both nuclear physics and astrophysics. The proposed activities will produce new scientists at the Ph.D. level, will give research experience in fundamental physics to undergraduate students, will continue to produce partnerships within the field to develop new detector technologies, and will contribute to the ascent of a large state university as a premier research institution. The advancement of the careers of women and ethnic minorities is an integral part of this process. Furthermore, the demand for state-of-the-art equipment utilizes the ASU research support services and the technical workforce of the society at large.

这项研究计划以解决核物理基本问题的实验为中心。正在设计一项实验，以寻找中子的非零电偶极矩，它的可能存在具有根本意义，并将极大地挑战基本粒子物理标准模型的理论扩展。另一项正在分析中的实验测量了电子-质子散射的二级效应，以解决目前质子结构数据中的一个难题。还有正在进行的冷中子实验，测量夸克之间弱相互作用的强度，随后将精确地测量控制中子衰变的参数，这可能对我们对核物理和天体物理的理解产生重要影响。拟议的活动将培养出新的博士水平的科学家，将为本科生提供基础物理方面的研究经验，将继续在该领域建立合作伙伴关系，开发新的探测器技术，并将有助于一所大型州立大学崛起为一流的研究机构。妇女和少数民族事业的发展是这一进程的一个组成部分。此外，对最先进设备的需求利用了亚利桑那州立大学的研究支持服务和整个社会的技术劳动力。
