This award will support a group of four highly experienced PI's to work on the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, Geneva, Switzerland, the European particle physics laboratory. The LHC machine and ATLAS detector were built using funds from the NSF and from other agencies around the world. It proved its worth three years ago when scientists discovered the Higgs Boson, the last particle in the historically successful "Standard Model" (SM) that accounts for so much of the known matter in the universe. In spite of its success, the Standard Model still leaves a number of questions about the fundamental structure of the universe unanswered, giving rise to research exploring Beyond the Standard Model (BSM). This award will allow the PI's to continue their leading role in studies of the Higgs width and couplings, properties that have so far established it as the SM object anticipated. It will also support their continuing search for BSM that could materialize at the higher energy experiments that are currently underway. The group supports a vigorous broader impact program. The centerpiece of this is a large, modular, multi-panel exhibit of ATLAS and the LHC. This has been used at major science festivals in NYC and Washington DC, and will be sent to other festivals around the country. They also plan to continue their leadership role in the ATLAS Zooniverse project, which allows the public to view and analyze ATLAS events. This project will be leveraged by the group's expertise in the operations of the ATLAS trigger, responsible for selection of the interesting reactions that occur in ATLAS. This becomes increasingly key to the physics potential of the LHC in Run2. In this run the LHC will operate at 13 TeV, almost double its currently highest energy of 8 TeV. In addition to conventional approaches to the trigger, and to enhancing sensitivity to new physics, the group will attempt prototyping new strategies such as "data scouting" that can fill holes in traditional off-line data analysis pipelines. They will also work on including the transverse momentum trigger, the trigger menu, trigger software, statistical methods and tools, analysis tools, pileup simulation techniques, and event visualization tools. They also plan detailed study of silicon detector properties using the infrastructure they have developed for the ATLAS upgrade.

该奖项将支持由四位经验丰富的 PI 组成的小组在欧洲粒子物理实验室瑞士日内瓦 CERN 的大型强子对撞机 (LHC) 上开展 ATLAS 实验。 LHC 机器和 ATLAS 探测器是使用 NSF 和世界各地其他机构的资金建造的。三年前，当科学家发现希格斯玻色子时，它证明了它的价值。希格斯玻色子是历史上成功的“标准模型”（SM）中的最后一个粒子，它解释了宇宙中大部分已知物质。 尽管取得了成功，标准模型仍然留下了许多关于宇宙基本结构的问题没有得到解答，从而引发了对超越标准模型（BSM）的研究探索。 该奖项将使 PI 能够继续在希格斯宽度和耦合的研究中发挥主导作用，这些特性迄今为止已将其确立为预期的 SM 物体。它还将支持他们继续寻找可在目前正在进行的高能实验中实现的 BSM。该组织支持一项强有力的、更广泛影响的计划。其核心是 ATLAS 和 LHC 的大型、模块化、多面板展览。这已在纽约和华盛顿特区的主要科学节上使用，并将发送到全国各地的其他节日。他们还计划继续在 ATLAS Zooniverse 项目中发挥领导作用，该项目允许公众查看和分析 ATLAS 事件。该项目将利用该小组在 ATLAS 触发器操作方面的专业知识，负责选择 ATLAS 中发生的有趣反应。这对于 Run2 中大型强子对撞机的物理潜力变得越来越关键。在这次运行中，LHC 将以 13 TeV 运行，几乎是目前最高能量 8 TeV 的两倍。 除了传统的触发方法以及增强对新物理的敏感性之外，该小组还将尝试设计新策略的原型，例如可以填补传统离线数据分析管道中的漏洞的“数据侦察”。他们还将致力于横向动量触发器、触发器菜单、触发器软件、统计方法和工具、分析工具、堆积模拟技术和事件可视化工具。他们还计划使用为 ATLAS 升级开发的基础设施来详细研究硅探测器的特性。
