This award funds the research activities of Professors Ayres Freitas and Adam Leibovich at the University of Pittsburgh.This purpose of this project is to develop improved theoretical tools and calculational methods for the robust, model-independent interpretation of results from current and future particle-physics experiments, both at the highest-energy colliders, such as the Large Hadron Collider, and for lower-energy precision measurements. The identification of a potentially small signal of new physics requires an excellent understanding of known particles and interactions. Furthermore, we will investigate techniques for model-independent descriptions of the effects of new physics, using a framework called "effective field theories". As a result, research in this area advances the national interest by promoting the progress of science in one of its most fundamental directions: the discovery and understanding of new physical laws. In conjunction with this effort, the PI's will also teach a special-topics course on effective field theories and precision physics. Both are topics that are often neglected in typical particle-physics textbooks. More technically, the research program can be divided into three main parts: (1) The development of calculational techniques for three-loop corrections to electroweak precision observables, and the integration of existing and new theoretical results for these observables into a flexible, object-oriented computer program; (2) The application of effective field theories, in particular Soft-Collinear Effective Theory, to unresolved questions at hadron colliders, such as processes involving jets, quarkonium production, and low-x physics; and (3) A comprehensive study of the use of effective field theories for new physics in Higgs, electroweak and flavor physics, with a focus on investigating correlations between operators, the role of different mass scales in the new-physics sector, and complications that arise in models of dark matter. This research plan is guided by ongoing and planned experimental high-energy physics efforts, and results will be made available to the experimental community in a suitable form.

该奖项为匹兹堡大学的Ayres Freitas和Adam Leibovich教授的研究活动提供资金。该项目的目的是开发改进的理论工具和计算方法，以对当前和未来的粒度物理学实验的结果进行稳健，独立的依赖模型的解释，同时是最高级别的collider，suker collider collider collider，sike collider colliser colliser instror colliser instror colliser and the hadron。 鉴定新物理学的潜在小信号需要对已知粒子和相互作用有很好的理解。 此外，我们将使用称为“有效的现场理论”的框架研究对新物理学影响的模型无关描述的技术。 结果，该领域的研究通过以最基本的方向之一促进科学进步来提高国家利益：对新物理定律的发现和理解。 结合这项工作，PI还将教授有关有效的现场理论和精确物理学的特殊主题课程。 两者都是典型的粒子物理教科书中通常被忽略的主题。 从技术上讲，研究计划可以分为三个主要部分：（1）开发三环校正以进行电子校正的计算技术，以及将这些可观察物的现有和新理论结果整合到一个灵活的，面向对象的计算机程序中的现有和新的理论结果； （2）将有效的现场理论（尤其是软共线理论）应用于强子山脉的未解决问题，例如涉及喷气机，Quarkonium生产和低X物理学的过程； （3）一项关于在希格斯，电动和风味物理学中使用有效的现场理论的全面研究，重点是研究操作员之间的相关性，不同质量尺度在新物理部门中的作用以及在暗物质模型中出现的并发症。 该研究计划以持续和计划的实验性高能物理工作为指导，结果将以合适的形式向实验社区提供。
