Roche and King plan a three-year research program focusing on the experimental study of the electro-weak structure of the proton at the Jefferson Laboratory. The project will provide data relevant to the quark flavor content of the proton (G0 experiment) and the correlation between the momentum and the spatial distributions of the quarks within the proton (DVCS experiment). Finally, this research will also contribute to the measurement of the weak charge of the proton (QWEAK experiment). This last measurement provides data relevant to the search for a new Standard Model of particle physics. Technically, the group will perform data analysis for G0, data acquisition and analysis projects for QWEAK and hardware development of the photon detector for DVCS. NSF also supports a graduate student and two undergraduate students to work on these research projects with King and Roche.

罗氏和金计划了一项为期三年的研究计划，重点是在杰斐逊实验室对质子的电弱结构进行实验研究。 该项目将提供与质子的夸克风味含量（G0实验）以及质子内夸克的动量和空间分布之间的相关性（DVCS实验）相关的数据。 最后，这项研究还将有助于质子弱电荷的测量（QWEAK实验）。最后的测量提供了与寻找新的粒子物理标准模型相关的数据。 技术上，该小组将进行G0的数据分析、QWEAK的数据采集和分析项目以及DVCS的光子探测器的硬件开发。 NSF 还支持一名研究生和两名本科生与 King 和罗氏一起开展这些研究项目。
