Multiple astronomical observations have established that about 85% of the matter in the universe is not made of known particles. Deciphering the nature of this so-called Dark Matter is of fundamental importance to cosmology, astrophysics, and high-energy particle physics. One of the most exciting quests in particle physics is the search for new particles beyond the Standard Model of particle physics. Extensions of the Standard Model predict not only new particles with large masses but also some with very small masses. Such a candidate is the axion, which has been introduced to explain the smallness of Charge-Parity (CP) violation in Quantum Chromodynamics and which turns out to also be a prime candidate for a constituent of the dark matter in the universe. The Axion Resonant InterAction DetectioN Experiment (ARIADNE) is designed to search for axion-mediated spin-dependent interactions between nuclei at sub-millimeter ranges. The experiment involves a rotating non-magnetic mass to source the axion field, and a dense ensemble of laser-polarized He-3 nuclei to detect the axion field by Nuclear Magnetic Resonance. While participating in this research, a team of postdocs, graduate students, and undergraduate researchers will be broadly trained in the techniques of experimental atomic physics, optical pumping, nuclear magnetic resonance, low-temperature physics, micro-fabrication, magnetic shielding, vacuum systems, and modeling. This will be valuable preparation for work in basic or applied research, either in the U.S. or international work force or scientific community.The signal from an axion field can be resonantly enhanced by properly modulating the axion potential at the nuclear spin precession frequency. The goal of this award is to complete construction of the experiment, bring it through its commissioning phase during which possible systematics will be evaluated, and start the early data taking stage, exploring new parameter space for the PQ axion. The method has the potential to improve previous experimental and astrophysical bounds on axions by several orders of magnitude and probe deep into the theoretically interesting regime for the PQ axion. The experiment is also sensitive to more exotic axion-like particles. The new method can ultimately exceed present laboratory constraints on spin-dependent short-range forces by up to 8 orders of magnitude and can improve on the combined laboratory/astrophysical limits by a factor of 10^4 in the axion mass range of ma between 10 micro-eV and 10 milli-eV, probing deep into the traditional "PQ-axion window".This 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.

多个天文观测已经确定，宇宙中大约85%的物质不是由已知粒子组成的。破译这种所谓的暗物质的性质对宇宙学、天体物理学和高能粒子物理学具有根本的重要性。粒子物理学中最令人兴奋的任务之一是寻找超越粒子物理学标准模型的新粒子。标准模型的扩展不仅预测了具有大质量的新粒子，而且预测了一些具有非常小质量的新粒子。轴子就是这样一个候选者，它被引入来解释量子色动力学中电荷宇称（CP）破坏的微小性，它也是宇宙中暗物质成分的主要候选者。Axion Resonant Interaction DetectioN Experiment（ARIADNE）旨在研究亚毫米级原子核之间的轴子介导的自旋相关相互作用。该实验涉及一个旋转的非磁性质量源的轴子场，和一个密集的合奏激光偏振的He-3核检测轴子场的核磁共振。在参与这项研究的同时，一个由博士后，研究生和本科生研究人员组成的团队将在实验原子物理学，光学泵浦，核磁共振，低温物理学，微制造，磁屏蔽，真空系统和建模技术方面进行广泛的培训。这将是有价值的准备工作，在基础或应用研究，无论是在美国或国际劳动力或科学界。来自轴子场的信号可以共振增强，通过适当地调制在核自旋旋进频率的轴子势。该奖项的目标是完成实验的建设，使其通过其调试阶段，在此期间可能的系统学将被评估，并开始早期数据采集阶段，探索PQ轴子的新参数空间。该方法有可能提高以前的实验和天体物理界的几个数量级的轴子和探测深入到理论上有趣的制度PQ轴子。该实验对更奇特的轴子粒子也很敏感。新方法最终可以超过目前实验室对自旋相关短程力的限制，最高可达8个数量级，并且可以将实验室/天体物理学的综合限制提高10^4倍，轴子质量范围在10微电子伏特和10毫电子伏特之间，对传统“PQ-轴子窗”的深入探讨该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的评估被认为值得支持。影响审查标准。
