Study of the electro-weak structure of the nucleon

罗奇和金计划一个为期三年的研究项目，重点是在杰斐逊实验室对质子的电弱结构进行实验研究。该项目将提供质子夸克风味含量（G0实验）和质子内夸克动量与空间分布的相关性（DVCS实验）的相关数据。最后，本研究也将有助于质子弱电荷的测量（QWEAK实验）。这最后一项测量为寻找粒子物理学的新标准模型提供了相关数据。在技术上，该小组将为G0进行数据分析，为QWEAK进行数据采集和分析项目，为DVCS进行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Roche一起进行这些研究项目。

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.
