The ATLAS physics program at the Large Hadron Collider (LHC) at CERN, Geneva, Switzerland is in full operation, with the LHC now delivering proton-proton collisions at 8 TeV collision energy. The NYU group continues to take a leading role in the implementation of the ATLAS detector's triggering system used to select collisions with large or imbalanced transverse momentum signatures. Through this program of effort, the NYU group proposes to continue its searches for new phenomena, to further develop statistical tools and techniques, and to maintain responsibility for the transverse energy trigger signatures. The group also aims to be a leader in a new analysis archival strategy and to continue R&D work on the tracker upgrade needed for the upgraded collider, the HL-LHC.Analytically, the group will leverage the expertise gained from measurement of the top-antitop production cross section in the dilepton final state to search for the Higgs boson and exotic physics in the top sector. If a new particle is discovered in searches for the Higgs boson, the group plans to use its expertise in statistical techniques and the vector boson fusion production mode to measure the new particle's properties and confirm if it is indeed responsible for electroweak symmetry breaking. NYU also plans to commission a new detector signature from highly collimated groups of leptons, a generic prediction from a class of models motivated by observations in dark matter searches. These analyses also provide the group with the depth and breadth of experience necessary to deal with surprises in the data.Technically, for upgrade of ATLAS, NYU has developed an IR-laser system for study of prototype silicon strip detectors to be used in the ATLAS upgrade required for the HL-LHC. It plans to develop a modified system to allow rapid tests of detectors read out with digital chips being developed by ATLAS/CERN.The NYU group is engaged in two distinct areas of broader impacts of their research effort. The first of these is the development a large exhibit on the LHC physics program for display at public events. The exhibit has been seen by thousands of people in diverse audiences in events in New York, Illinois, and California. The group proposes to extend this public outreach by further developing this exhibit, adding new interactive components and updated results. This will be done with the involvement of educators and students from the NYU Department of Teaching and Learning, who will help make this exhibit even more accessible to the K-12 population. The exhibit will be shown at science fairs and other venues.For the second effort, the NYU group is actively involved in the important area of Data Preservation and Open Access. The statistical tools (under the name RECAST) that continue to be developed as part of this proposal have broader impacts within the physics community, and are gaining attention outside of physics as well. The question of how to archive data in high energy physics that allows future use (such as confronting new theories with preexisting data) is a daunting one, as the expertise and software required to do such analysis fade with time. The RECAST framework proposed by the NYU group represents a new approach to data management and access, which can address a crucial issue for the LHC and serve as a model for a broad range of scientific disciplines.

瑞士日内瓦州CERN的大型强子对撞机（LHC）的Atlas物理计划正在全部运行，LHC现在在8 TEV Collision Energy提供质子 - 普罗顿碰撞。 纽约大学集团继续在ATLAS检测器的触发系统的实施中发挥领导作用，用于选择具有较大或不平衡的横向动量签名的碰撞。 通过这项努力计划，纽约大学小组提议继续寻找新现象，进一步开发统计工具和技术，并保持对横向能量触发签名的责任。该小组还旨在成为新的分析档案策略的领导者，并继续在升级后的对撞机所需的跟踪器升级上进行研发工作，HL-LHC.Analytlythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythalythallythalythalythallythalythallythallythallythallyt the小组将利用从顶级距离的最高攻击中获得的专业知识DiLepton最终状态的生产横截面以在顶部搜索Higgs玻色子和外来物理。如果在搜索希格斯玻色子时发现了一个新粒子，则该小组计划在统计技术方面使用其专业知识和向量玻色子融合生产模式来测量新粒子的特性，并确认它是否确实负责电动electroweak对称性破坏。 纽约大学还计划从高度准直的Leptons群体中委托新的检测器签名，这是由一系列模型的通用预测，这些模型是由暗物质搜索中观察到的一系列模型。这些分析还为小组提供了应对数据中惊喜所需的深度和广度。从技术上讲，纽约大学（NYU HL-LHC所需的升级。它计划开发一个修改的系统，以允许通过Atlas/Cern开发数字芯片来快速测试探测器。纽约大学集团参与了他们研究工作的更广泛影响的两个不同领域。首先是开发项目，其中一个大型展览在LHC物理计划上进行公共活动展示。在纽约，伊利诺伊州和加利福尼亚州的活动中，成千上万的观众中有成千上万的人看到了该展览。该小组建议通过进一步开发该展览，添加新的交互式组件和更新的结果来扩展这种公众范围。这将通过纽约大学教学和学习部的教育工作者和学生的参与来完成，这将帮助使K-12人口更容易获得该展览。展览将在科学博览会和其他场所展出。第二次努力，纽约大学集团积极参与数据保存和开放访问的重要领域。 作为该提案的一部分，继续开发的统计工具（以重新铸造为名）在物理界产生了更广泛的影响，并且在物理学之外也引起了人们的关注。如何在高能量物理学中存档数据的问题（例如与已有数据与新理论面对新理论）的问题是令人生畏的，因为进行此类分析所需的专业知识和软件会随着时间的推移而淡出。 NYU集团提出的重铸框架代表了一种新的数据管理和访问方法，该方法可以解决LHC的关键问题，并作为广泛科学学科的模型。
