This project uses the unique data set acquired by the gigaton-scale IceCube Neutrino Observatory, located at the South Pole, to explore for signatures of new physics. The IceCube data set comprises the highest energy neutrino interactions observed on Earth. The neutrino interactions to be used in the analyses supported by this grant are in a range that is x20 to x200 higher than the highest energy accelerator-produced neutrino interactions produced today. Because signatures for Beyond Standard Model Physics are expected to become more apparent with energy, IceCube data opens a new window on a rich array of predicted Beyond Standard Model effects, as well as an opportunity to follow up on anomalous behavior that may point to new physics. The group will continue and expand upon the very successful CosmicWatch program that provides instructions for building simple muon detectors that can be used for teaching and other outreach activities. The project will allow for the first high-energy, full three-flavor search for Beyond Standard Model signatures in neutrino physics utilizing flavor-tagged events in the 1 to 100 TeV-scale. IceCube has the unique capability of observing resonance signatures of matter effects induced if neutrinos with exotic properties pass through the dense Earth. The analysis will expand a data set developed by the PIs since 2014 that unites the Neutrino, Energy, Cosmic, and Rare Process Frontiers. The data set will reach 100~TeV and comprise more than one million upward-going neutrino events flavor identified on an event-by-event basis. The flux sources in the sample are atmospheric neutrinos and a highly-enriched astrophysical sample isolated through directional information - the first high-purity astrophysical sample below 60 TeV.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.

该项目利用位于南极的十亿吨级冰立方中微子观测站获得的独特数据集，探索新物理学的特征。冰立方数据集包含在地球上观测到的最高能量中微子相互作用。该基金支持的分析中使用的中微子相互作用比目前产生的最高能量加速器产生的中微子相互作用高20到200倍。由于超越标准模型物理的特征预计会随着能量的增加而变得更加明显，冰立方的数据为预测的丰富的超越标准模型效应打开了一扇新窗口，同时也为跟踪可能指向新物理学的异常行为提供了机会。该小组将继续并扩展非常成功的宇宙观察项目，该项目为建立简单的μ子探测器提供指导，这些探测器可用于教学和其他推广活动。该项目将允许在1到100 tev尺度上利用风味标记事件，首次对中微子物理中的超越标准模型特征进行高能、完整的三风味搜索。冰立方具有独特的观测能力，可以观察到具有奇异性质的中微子穿过致密的地球时所引起的物质效应的共振特征。该分析将扩展pi自2014年以来开发的数据集，该数据集将中微子、能量、宇宙和稀有过程前沿结合起来。数据集将达到100~TeV，包括超过一百万个向上的中微子事件，这些中微子事件是在一个事件一个事件的基础上确定的。样品中的通量源是大气中微子和通过定向信息分离出的高富集天体物理样品，这是第一个低于60 TeV的高纯度天体物理样品。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
