项目摘要
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.
该项目使用位于南极的十亿吨级IceCube中微子天文台获得的独特数据集来探索新物理学的特征。IceCube数据集包括地球上观测到的最高能量中微子相互作用。在这项资助支持的分析中使用的中微子相互作用比今天产生的最高能量加速器产生的中微子相互作用高出20到200倍。由于超越标准模型物理学的特征预计将随着能量的增加而变得更加明显,IceCube数据为预测的一系列丰富的超越标准模型效应打开了一个新的窗口,并有机会跟进可能指向新物理学的异常行为。 该小组将继续并扩大非常成功的CosmicWatch计划,该计划为建造可用于教学和其他推广活动的简单μ子探测器提供指导。 该项目将允许在中微子物理学中利用1至100 TeV尺度的味道标记事件进行第一次高能量,完整的三味搜索超越标准模型签名。IceCube具有独特的能力,可以观测具有奇异性质的中微子穿过致密地球时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。该数据集将达到100~TeV,包括超过100万个按事件识别的上行中微子事件。样品中的通量源是大气中微子和通过方向信息分离的高度富集的天体物理样品-第一个低于60 TeV的高纯度天体物理样品。该奖项反映了NSF的法定使命,并被认为值得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来支持。
