Collaborative Research: Beyond Standard Model Searches Using the IceCube Neutrino Telescope

该项目使用位于南极的千兆级冰立方中微子天文台获得的独特数据集，以探索新物理的特征。冰立方数据集包括地球上观测到的能量最高的中微子相互作用。这笔赠款支持的分析中使用的中微子相互作用的范围比目前由加速器产生的最高能量的中微子相互作用高出20到200倍。由于超越标准模型物理的信号预计将随着能量的增加而变得更加明显，冰立方数据为一系列丰富的预测的超越标准模型效应打开了一个新的窗口，并提供了一个机会来跟踪可能指向新物理的异常行为。该小组将继续并扩展非常成功的宇宙观察计划，该计划提供了建造可用于教学和其他外展活动的简单Muon探测器的指导。该项目将利用1到100 TeV尺度上的气味标记事件，首次实现对中微子物理学中超越标准模型签名的高能、完整的三味搜索。冰立方具有独特的能力，可以观测到具有奇异性质的中微子穿过致密地球时所产生的物质效应的共振特征。这项分析将扩展PIS自2014年以来开发的数据集，该数据集将中微子、能源、宇宙和稀有过程前沿统一在一起。数据集将达到100~TeV，包括逐个事件识别的100多万个向上中微子事件。样本中的通量源是大气中微子和通过定向信息隔离的高度浓缩的天体物理样本--第一个低于60TeV的高纯度天体物理样本。该奖项反映了NSF的法定使命，并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，被认为值得支持。

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.
