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支持实验的修正，如寻找标准模型以外的物理信号的宇称破坏电子散射;精确计算对核子质量的电磁修正，说明我们最近对核子结构的所有了解;研究扭曲光子态的潜在核物理应用，扭曲光子态是携带非常高角动量的光子态;继续从描述我们世界核相互作用的规范理论与更高维度引力理论模型之间的显着对应性中获得强子理论结果;并利用核物理知识精确地获得原子能分裂的重要核尺寸修正。这些项目将有助于弥合差距强子理论（通过强力或核力相互作用的粒子）与观察到的现象之间的联系，并导致对强子反应机制的更深入理解。 一个项目还将连接到另一个领域，原子物理学领域。 他们还将培训包括本科生在内的新生。 PI有两个成功的女博士。目前的项目可以扩大妇女进入该领域的机会。 PI定期在杰斐逊实验室工作，弥合大学和国家实验室之间以及数据和理论之间的差距。
