Abstract

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory provides an intense, high-quality source of neutrinos from pion decay at rest. This source was recently used for the first measurements of coherent elastic neutrino–nucleus scattering (CEvNS) by the COHERENT Collaboration, which resulted in new constraints of physics beyond the Standard Model. The SNS neutrino source will enable further CEvNS measurements, exploration of inelastic neutrino–nucleus interactions of particular relevance for understanding supernova neutrinos, and searches for accelerator-produced sub-GeV dark matter. Taking advantage of this unique facility, COHERENT's suite of detectors in Neutrino Alley at the SNS is accumulating more data to address a broad physics program at the intersection of particle physics, nuclear physics, and astrophysics. This review describes COHERENT's first two CEvNS measurements, their interpretation, and the potential of a future physics program at the SNS. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 73 is September 2023.

散裂中子源的相干

橡树岭国家实验室的散裂中子源(SNS)从静止的介子衰变中提供了一个强烈的、高质量的中微子源。该源最近被相干协作用于相干弹性中微子核散射(CEvNS)的首次测量，这导致了超出标准模型的新的物理约束。SNS中微子源将支持进一步的CEvNS测量，探索与理解超新星中微子特别相关的非弹性中微子-核相互作用，以及搜索加速器产生的亚gev暗物质。利用这一独特的设施，COHERENT在SNS中微子巷的探测器套件正在积累更多的数据，以解决粒子物理学、核物理学和天体物理学交叉领域的广泛物理项目。这篇综述描述了COHERENT的前两次CEvNS测量，它们的解释，以及SNS未来物理项目的潜力。预计《核与粒子科学年度评论》第73卷的最终在线出版日期为2023年9月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
