In the next few years, the experiments at the Large Hadron Collider (LHC) at CERN will for the first time probe the electroweak scale directly. The LHC data will certainly trigger dramatic progress in our understanding of physics at this scale. The main goal of the PI?s research in the LHC era will be to contribute to this progress by providing theoretical interpretation of the data. His research will be data-driven. The projects include understanding the ?space of possibilities? for new physics. Some of his immediate efforts will be focused on building and analyzing candidate models. His research will be involves in understanding which observables can be used to discriminate between various proposed models, and, once the correct model is established, to determine its parameters. The PI has investigated collider phenomenology related to a variety of new physics scenarios, including supersymmetry, models with extra dimensions, Little Higgs models, and Higgs-less models. His present proposal includes several new projects in this area, including a study of new observables that can provide unique measurements of s-top-sector parameters in supersymmetric models; a novel phenomenological framework for describing the Regge states in Randall-Sundrum models and analyzing their LHC signatures; and a test-case analysis of the power of the LHC to discriminate between models with similar signatures, such as supersymmetry and the Little Higgs with T parity. As far as broader impacts and outreach, the PI proposes to organize professional development workshops for science teachers in rural upstate New York areas which are adversely affected by economic and geographic factors. In collaboration with Lora Hine, the full-time outreach coordinator at the Cornell Laboratory for Elementary Particle Physics (LEPP), the PI intends to organize one-day professional development workshops that would bring K-12 science teachers from such districts to the Cornell campus. The workshops would include tours of CESR or other scientific facilities, presentations by Cornell scientists including the PI as well as sessions to help teachers develop lesson plans. This project would use the extensive outreach infrastructure that already exists at LEPP. In addition, the PI will perform follow-up visits to schools to observeand evaluate the use of the materials and lesson plans in the classroom, and to provide additional support for the teachers as necessary. The second area, which the PI is involved in is educating the public about the impact that particle physics is making on society through transfer of technologies originally developed for particle physics. The PI hopes to document the history of the known examples of technology transfer and hopes to explain how the unique environment of particle physics research made these advances possible The PI also participates in the Research Experience for undergraduates (REU) program at LEPP both as a mentor and as a lecturer. A significant fraction of the students in this program come from small liberal-arts colleges and other institutions with few research opportunities.

在接下来的几年里，欧洲核子研究中心的大型强子对撞机（LHC）的实验将首次直接探测电弱尺度。大型强子对撞机的数据肯定会在我们对这种规模的物理学的理解上引发巨大的进步。PI的主要目标是什么？在LHC时代的研究将通过提供数据的理论解释来促进这一进步。他的研究将以数据为基础。这些项目包括了解？可能性的空间？对于新物理。他近期的一些工作将集中在构建和分析候选模型上。他的研究将包括了解哪些可观测值可以用来区分各种提出的模型，一旦建立正确的模型，确定其参数。PI研究了与各种新物理场景相关的对撞机现象学，包括超对称、额外维度模型、小希格斯模型和无希格斯模型。他目前的建议包括该领域的几个新项目，包括研究可以提供超对称模型中s-顶扇区参数独特测量的新可观测物；描述Randall-Sundrum模型中的Regge态并分析其LHC特征的一种新的现象学框架；以及对大型强子对撞机的能力进行测试分析，以区分具有相似特征的模型，例如超对称和具有T宇称的小希格斯。就更广泛的影响和推广而言，PI建议为受到经济和地理因素不利影响的纽约州北部农村地区的科学教师组织专业发展讲习班。与康奈尔大学基本粒子物理实验室（LEPP）的全职外延协调员劳拉·海因（Lora Hine）合作，PI打算组织为期一天的专业发展研讨会，将这些地区的K-12科学教师带到康奈尔大学校园。这些研讨会将包括参观CESR或其他科学设施，康奈尔大学科学家（包括PI）的演讲，以及帮助教师制定课程计划的会议。该项目将使用LEPP已经存在的广泛的外联基础设施。此外，教官会到学校进行跟进访问，观察和评估教材和教案在课堂上的使用情况，并在必要时为教师提供额外的支持。第二个领域，PI参与的是教育公众关于粒子物理通过转移最初为粒子物理开发的技术对社会产生的影响。PI希望记录已知的技术转移案例的历史，并希望解释粒子物理研究的独特环境如何使这些进步成为可能。PI还作为导师和讲师参加了LEPP的本科生研究经验（REU）计划。这个项目的很大一部分学生来自小型文理学院和其他研究机会很少的机构。
