项目摘要

The goals of the project are to calculate corrections in support of experiments such as parity violating electron scattering that are searching for signals of physics beyond the standard model; to calculate accurately electromagnetic corrections to nucleon masses accounting for all we have learned about nucleon structure in recent times; to study potential nuclear physics applications of twisted photon states, which are photon states that carry very high angular momentum; to continue obtaining hadron theory results from the remarkable correspondence between the gauge theories that describe nuclear interaction in our world and theoretical models of gravity in higher dimensions; and to use nuclear physics knowledge to accurately obtain important nuclear size corrections to atomic energy splittings.These projects will help bridge the gap between the theory of hadrons (particles that interact via the strong, or nuclear, force) and observed phenomena, and lead to greater understanding of the mechanisms of hadronic reactions. One project will also connect to another field, the field of atomic physics. They will also train new students, including undergraduates. The PI has had two successful women Ph. D. students, and the present project may extend opportunities for women entering the field. The PI is regularly at the Jefferson Laboratory and bridging the gap between university and national lab as well as between data and theory.

该项目的目标是计算校正以支持实验，例如违反电子散射，这些散射正在寻找超出标准模型以外的物理信号；为了计算准确的电磁校正到核子质量的核能，涉及我们最近了解的有关核子结构的所有内容；研究扭曲光子状态的潜在核物理应用，即具有很高角动量的光子状态；继续从描述我们世界中核相互作用的量学理论与更高维度重力的理论模型之间的显着对应关系获得强调理论。并使用核物理知识准确地获得了原子能分裂的重要核大小校正。这些项目将有助于弥合Hadron的理论（通过强或核，力相互作用）和观察到的现象之间的差距，并提高人们对Hadronic反应机制的更多了解。一个项目还将连接到另一个领域，即原子物理领域。他们还将培训包括本科生在内的新学生。 PI有两名成功的女性博士学位学生，目前的项目可能会为妇女进入该领域的机会。 PI定期在杰斐逊实验室，并弥合大学和国家实验室之间以及数据与理论之间的差距。
