Theoretical Study of Nucleon Structure and Hadronic Interactions

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。组成原子核的中子和质子是由夸克组成的。我们研究这个夸克子结构在核物理中是如何出现的。我们专注于电荷对称的测试，如果质子和中子相同，这将是准确的。我们研究束缚原子核的强作用力的细节，集中在观察所有最终反应产物的反应上。我们进行电子或原子在小型二维纳米级系统中运动的模拟，其中粒子的波动性质产生了很大的影响。更广泛的影响包括培养本科生和博士后，使他们成为应用于技术、国防、通信和金融的复杂系统的专家。最近的博士后中有几名女性。PI为非科学家举办关于物理学进展的研讨会，提高普通大众的科学素养。PI和他的学生在儿童科学博物馆做志愿者。他参加了一项为期一年的研究“科学与美国公共民主”。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Neutrons and protons, the constituents of the atomic nucleus, are composed of quarks. We study how this quark substructure appears in nuclear physics. We focus on tests of charge symmetry, which would be exact if protons and neutrons were identical. We study details of the strong force binding the atomic nucleus, concentrating on reactions where one observes all final reaction products. We carry out simulations of electrons or atoms moving in small two-dimensional nanoscale systems, where the wave nature of particles produces large effects. Broader impacts involve training of undergraduates and postdocs, who become expert in complex systems with application to technology, defense, communications and finance. Recent postdocs have included several women. The PI gives seminars on advances in physics for non-scientists, increasing scientific literacy in the general population. The PI and his students volunteer at a children's science museum. He participated in a year-long study "Science and American Public Democracy."
