Fundamental Research in Nuclear Physics

这个研究计划的中心是解决核物理基本问题的实验。正在设计一个实验来寻找中子的非零电偶极矩，它的可能存在是一个基本的兴趣，并将极大地挑战基本粒子物理标准模型的理论扩展。另一个正在分析的实验测量了电子-质子散射中的二阶效应，以解决目前质子结构数据上的一个难题。还有正在进行的用冷中子测量夸克之间弱相互作用强度的实验，随后是对控制中子衰变参数的精确新测量，这对我们对核物理和天体物理的理解都有重要影响。这些活动将培养出博士级别的新科学家，将为本科生提供基础物理学的研究经验，将继续在该领域内建立合作伙伴关系，以开发新的探测器技术，并将有助于将一所大型州立大学提升为一流的研究机构。提高妇女和少数民族的职业地位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。

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.
