With the Compact Muon Solenoid Experiment at the Large Hadron Collider at CERN, Geneva, Switzerland, the range and scope of possible new physics signatures is vast. The Vanderbilt High Energy Physics group has carefully designed a science roadmap that tackles promising and physically well-motivated models/theories, while maintaining sensitivity to more general exotic signatures. This program capitalizes on their established expertise in tau lepton reconstruction and identification and their growing expertise in top quark physics. They exploit this focused toolset to perform searches for physics beyond the Standard Model (BSM), targeting interesting new physics such as the so far elusive Higgs boson, new high mass resonances, Supersymmetry, grand unification of the fundamental forces, and dark matter. This program of utilizing tau and top expertise to search for new physics also provides the backbone for a more extensive long-term vision aimed at providing precision measurements that will help the physics community distinguish between the vast range of physics models.In broader impacts of their research effort, the Vanderbilt HEP group's collaborative efforts with computer scientists are breaking new ground in the area of data logistics through two projects funded by separate NSF awards: REDDnet and DYNES. REDDnet is designed to provide a large distributed storage facility for data intensive collaboration among the nations researchers and educators in a wide variety of application areas. Its mission is to provide working storage to help manage the logistics of moving and staging large amounts of data in the wide area network. REDDnet is serving researchers from a wide variety of application domains, including a digital archive project in the Library of Congress, the Large Synoptic Survey Telescope project, and HEP. DYNES is a nationwide cyber-instrument spanning about forty US universities and eleven Internet2 connectors. A collaborative team including Internet2, Caltech, the University of Michigan, and Vanderbilt University is working to support large, long-distance scientific data flows from the LHC and other leading programs in data intensive science. The Vanderbilt HEP group has also led a Vanderbilt campus-wide effort to develop a researcher-driven campus-computing center. The Vanderbilt HEP group benefits greatly from the participation of undergraduates in their program. And the group is operating a very active local QuarkNet center that has been an important component of the national QuarkNet Program for nearly a decade.

随着瑞士日内瓦欧洲核子研究中心大型强子对撞机的紧凑μ子螺线管实验，可能的新物理特征的范围和范围是巨大的。 范德比尔特高能物理小组精心设计了一个科学路线图，解决了有前途的和物理上动机良好的模型/理论，同时保持对更一般的外来签名的敏感性。该计划利用了他们在τ轻子重建和识别方面的专业知识以及他们在顶夸克物理学方面不断增长的专业知识。他们利用这个集中的工具集来搜索标准模型（BSM）之外的物理学，目标是有趣的新物理学，如迄今为止难以捉摸的希格斯玻色子，新的高质量共振，超对称性，基本力的大统一和暗物质。这个利用tau和顶级专业知识来寻找新物理的计划也为更广泛的长期愿景提供了支柱，旨在提供精确的测量，这将有助于物理学界区分各种物理模型。在他们研究工作的更广泛影响中，范德比尔特HEP小组与计算机科学家的合作努力正在通过两个项目在数据物流领域开辟新的天地，这两个项目由单独的NSF奖项：REDDnet和Dynes。REDDnet旨在为各国研究人员和教育工作者在各种应用领域开展数据密集型合作提供一个大型分布式存储设施。它的使命是提供工作存储，以帮助管理广域网中移动和暂存大量数据的物流。REDDnet正在为来自各种应用领域的研究人员提供服务，包括美国国会图书馆的数字档案项目、大型综合巡天望远镜项目和高能物理项目。 DYNES是一个全国性的网络工具，覆盖了大约40所美国大学和11个Internet 2连接器。一个包括Internet 2、加州理工学院、密歇根大学和范德比尔特大学在内的合作团队正在努力支持来自大型强子对撞机和其他数据密集型科学领先项目的大规模、长距离科学数据流。范德比尔特HEP小组还领导了一个范德比尔特校园范围内的努力，以开发一个研究人员驱动的校园计算中心。范德比尔特HEP小组从本科生参与他们的项目中受益匪浅。该组织正在运营一个非常活跃的当地QuarkNet中心，该中心近十年来一直是国家QuarkNet计划的重要组成部分。
