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.

散裂中子源的相干性


橡树岭国家实验室的散裂中子源 （SNS） 为静止时 π 衰变提供了强烈、高质量的中微子来源。该源最近被 COHERENT Collaboration 用于相干弹性中微子-核散射 （CEvNS） 的首次测量，这导致了标准模型之外的物理学的新约束。SNS 中微子源将使进一步的 CEvNS 测量成为可能，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，并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 的 Neutrino Alley 的探测器套件正在积累更多数据，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学项目。这篇综述描述了 COHERENT 的前两个 CEvNS 测量、它们的解释以及 SNS 未来物理学项目的潜力。
