CAREER: Theoretical Applications of Effective Field Theories for Current and Future Experiments

对当前和未来粒子物理实验的重要理论问题将以软共线有效理论（SCET）为中心工具进行研究。重夸克的深度非弹性散射，扩展到对希格斯和单顶生产很重要的强子碰撞，以及电弱Sudakov对数将使用SCET计算。虽然低质量胶子的存在是不受欢迎的，但它还没有被排除。在大型强子对撞机中，由轻胶子引起的实验特征（如果它存在的话）将被研究，希望能有一个发现，或者找到一种方法来排除参数空间的这个角落。将计算J/psi的光产和电产，目前的理论预测与数据不太吻合。夸克衰变将使用SCET进行计算，而SCET的理论又与实际数据不一致。对NRQCD矩阵元素的普适性问题进行了严格的研究。这项提案计划在匹兹堡大学的物理课程中引入新的、积极的教学方法。这将随后扩展到K-12教师和学生。一个特殊的教室将被创建，旨在鼓励主动学习。这个学习空间将使传统的讲座和实验室形式相结合。该教室将作为一个试点班级，然后融入K-12科学教师的教学，如下所示。本科物理课程第一和第二学期的试点课程将是高度协作、动手、计算机丰富和互动的。此外，还将与匹兹堡大学教育学院合作，为职前教师开设基础科学方法课程。将与匹兹堡公立学区一起设立为期一周的暑期物理学院，为K-12教师教授物理。最后，通过匹兹堡大学的GK-12项目，将对K-12学生进行讲座。

Theoretical issues of importance to current and future particle physics experiments will be examined using soft-collinear effective theory (SCET) as the central tool . Deep-inelastic scattering with heavy quarks, with extension to hadron collisions important for Higgs and single-top production, and Electroweak Sudakov logarithms will be calculated using SCET. While the existence of a low-mass gluino is disfavored, it has not yet been ruled out. Experimental signatures at the LHC due to the light gluino, if it exists, will be investigated, in the hopes of either a discovery or a way to rule out this corner of parameter space. Photoproduction and electroproduction of J/psi will be calculated, where current theoretical predictions do not fit the data well. Quarkonium decays will be calculated using SCET, where again the theory does not agree with data. The question of the universality of NRQCD matrix elements will be rigorously studied. This proposal plans the introduction of new, active teaching methods into the physics curriculum at the University of Pittsburgh. This will be followed with the extension to K-12 teachers and students. A special classroom will be created, designed to encourage active learning. This learning space will enable the traditional lecture and laboratory format to be combined. The classroom will be used for a pilot class and then integrated into the teaching of K-12 science teachers as follows. The pilot class, for the first and second semester undergraduate physics course, will be highly collaborative, hands-on, computer-rich, and interactive. In addition, lectures will be given in the Elementary Science Methods class to pre-service teachers jointly with the University of Pittsburgh's School of Education. A week long summer institute for teaching physics to K-12 teachers will be set up with the Pittsburgh Public School District. Finally, lectures through the GK-12 program at the University of Pittsburgh will be given to K-12 students.
