Investigations in High Energy Physics

该奖项资助匹兹堡大学的Adam Leibovich和Ayres Frietas教授的研究活动。大型强子对撞机(LHC)目前正在以惊人的速度获取数据。这些数据将使粒子物理学家能够探索“标准模型”，这是目前对物质的基本相互作用和组成部分的最好理解。由于大型强子对撞机以比之前探索的更高的能量获取数据，因此有可能发现超越标准模型的物理。这个项目将在一定程度上专注于可以在大型强子对撞机上探测的超标准模型物理的签名。我们的目标是找到方法来确定新的非标准模型粒子的性质，如质量和自旋，即使我们不知道新的物理是什么。该项目还将侧重于改进各种粒子物理信号计算的理论技术，包括计算高阶微扰修正、对无限修正级数求和以及追求路径积分技术。预计该项目还将产生更广泛的重大影响。建议的项目非常适合不同水平的学生参与，让他们获得理论物理、数学方法、计算机编程和数据分析方面的知识和技能。该项目还与实验高能物理和宇宙学有重要联系，从而加强了这些不同专业领域之间的协同效应。最后，本文研究的计算技术在其他物理领域也有应用，如广义相对论和流体力学。

This award funds the research activities of Professors Adam Leibovich and Ayres Frietas at the University of Pittsburgh. The Large Hadron Collider (LHC) is currently taking the data at a remarkable rate. This data will allow particle physicists to probe the "Standard Model", which is the best current understanding of the fundamental interactions and building blocks of matter. Since the LHC is taking data at a higher energy than has previously been explored, it is possible that physics beyond the Standard Model will be discovered. This project will in part focus on signatures for beyond-the-Standard-Model physics that can be probed at the LHC. The goal is to find ways to determine properties of new non-Standard Model particles, such as mass and spin, even if we do not know what the new physics happens to be. This project will also focus on theoretical techniques to improve calculations of various particle-physics signals, including calculating higher-order perturbative corrections, summing infinite series of corrections, and pursuing path-integral techniques. This project is also envisioned to have significant broader impacts. The proposed project is well suited for the participation of students at different levels, allowing them to acquire knowledge and skills in theoretical physics, mathematical methods, computer programming and data analysis. This project also has important connections to experimental high-energy physics and cosmology, thus strengthening synergistic effects between these different fields of specialization. Finally, the calculational techniques studied here also have applications in other fields of physics, such as general relativity and fluid dynamics.
