One of the major intellectual achievements of the 20th century was the development of the Standard Model (SM) of particle physics. This model succeeded in classifying all of the elementary particles known at the time into a hierarchy of groups having similar quantum properties. The validity of this model to date was confirmed by the discovery of the Higgs boson at the Large Hadron Collider at CERN. However, the Standard Model as it currently exists leaves open many questions about the universe, including such fundamental questions as to why the Higgs mass has the value it has and why there is no antimatter in the universe. A primary area to search for answers to these and other open questions about the universe, how it came to be and why it is the way it is, is to focus on a study of the properties of neutrinos and to use what we know and can learn about neutrinos as probes of science beyond the Standard Model. Neutrinos are those elementary particles that interact with practically nothing else in the universe. They have no electric charge and were once thought to be massless. Like other elementary particles, they were believed to have an antimatter counterpart, the antineutrino. Moreover, the Standard Model predicted that there were actually three different kinds of neutrinos that were distinguishable through the different interactions that they did undergo whenever there was an interaction. But recent measurements have totally changed our picture of neutrinos. We now know that neutrinos do have a mass and because they do, they can actually change from one type to another. The Intellectual Merit of this work is in the detailed measurements of these changes, along with other current neutrino experiments. These form one of the most promising ways to probe for new physics Beyond the Standard Model (BSM) and are the subject of this investigation. This research will involve the work of undergraduate students at the University of Minnesota, Duluth, an RUI. Faculty and students working on the NOvA and MINERvA experiments will further the neutrino oscillation measurements and are working toward first astrophysics results. The effort includes enhancing the ability for NOvA electronics to self-detect the neutrino burst from a potential galactic supernova and share that alert with the world-wide supernova detection network. Neutrino interaction measurements continue with existing and incoming data from the MINERvA experiment. Finally, the group is pursuing work toward the next generation experiment, DUNE, including roles in the data acquisition system, design of the near detectors, and the role of neutrino interaction uncertainties in the design sensitivity of the experiment. This grant also supports broader impacts via participation and leadership of the NOvA outreach program, which includes regular summer tours of the Soudan Underground Laboratory and the NOvA detector at the Ash River, MN site.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.

20 世纪的主要智力成就之一是粒子物理学标准模型 (SM) 的发展。该模型成功地将当时已知的所有基本粒子分类为具有相似量子特性的群的层次结构。迄今为止，欧洲核子研究中心大型强子对撞机希格斯玻色子的发现证实了该模型的有效性。然而，目前存在的标准模型留下了许多关于宇宙的问题，包括为什么希格斯质量具有它所具有的价值以及为什么宇宙中没有反物质等基本问题。寻找这些和其他有关宇宙、宇宙是如何形成以及为何成为现在这个样子的开放性问题的答案的一个主要领域是集中研究中微子的性质，并利用我们所知道和能够做到的了解中微子作为标准模型之外的科学探针。中微子是那些几乎不与宇宙中其他任何物质相互作用的基本粒子。它们不带电荷，曾经被认为没有质量。与其他基本粒子一样，它们被认为具有反物质对应物，即反中微子。此外，标准模型预测实际上存在三种不同类型的中微子，可以通过它们在相互作用时所经历的不同相互作用来区分。但最近的测量完全改变了我们对中微子的看法。我们现在知道中微子确实有质量，并且因为有质量，它们实际上可以从一种类型转变为另一种类型。这项工作的智力价值在于对这些变化以及当前其他中微子实验的详细测量。 这些构成了探索标准模型（BSM）之外的新物理学最有前途的方法之一，也是本次研究的主题。这项研究将涉及明尼苏达大学德卢斯分校 (RUI) 本科生的工作。从事 NOvA 和 MINERvA 实验的教师和学生将进一步进行中微子振荡测量，并致力于获得第一个天体物理学结果。这项工作包括增强 NOvA 电子设备自我检测潜在银河超新星中微子爆发的能力，并与全球超新星检测网络共享该警报。中微子相互作用测量继续使用 MINERvA 实验的现有数据和传入数据。最后，该小组正在致力于下一代实验 DUNE，包括数据采集系统中的作用、近探测器的设计以及中微子相互作用不确定性在实验设计灵敏度中的作用。这笔赠款还通过参与和领导 NOvA 外展计划来支持更广泛的影响，其中包括定期夏季参观 Soudan 地下实验室和位于明尼苏达州阿什河的 NOvA 探测器。该奖项反映了 NSF 的法定使命，并被认为是值得的通过使用基金会的智力优势和更广泛的影响审查标准进行评估来提供支持。
