Experimental Nuclear Physics Research Program

马里兰大学实验核物理小组将开展一项研究计划，重点是利用电弱相互作用来研究基于夸克的核子结构。将特别强调两个主要主题：使用违反宇称的电子散射来测量由弱相互作用所看到的质子的结构，以及使用极化观测值来精确测量质子和中子的电磁结构。第一个主题的主要组成部分是能源部杰斐逊实验室的G0实验，该实验是一个多年计划的大约一半，该计划旨在测量在广泛的动量转移范围内奇怪的夸克对核子结构的贡献。整个研究计划的第二个主要组成部分是将对中子电荷分布的测量扩展到比以前可以实现的更高的动量结构，从而缩短距离。该小组的工作将继续开发和维护用于他们在杰斐逊实验室的实验的仪器，以及分析数据和解释结果。该小组将向一些本科生和研究生提供研究机会。

The University of Maryland Experimental Nuclear Physics group will carry out program of research focused on the use of electroweak interactions to study the quark-based structure of nucleons. Particular emphasis will be placed on two major themes: the use of parity violating electron scattering to measure the structure of the proton as seen by weak interactions, and the use of polarization observables to provide precise measurements of the electromagnetic structure of both the proton and neutron. The primary component of the first theme is the G0 experiment at the DOE Jefferson Laboratory, which is about half-way through a multiyear program to measure the strange quark contributions to the nucleon structure over a wide range of momentum transfer. The second main component of the overall research program is to extend the measurement of the neutron's charge distribution to significantly higher momentum structure, and thus shorter distances, than has previously been achievable. The group's work will continue to development and maintain instrumentation for use on their experiments at Jefferson laboratory, as well as to analyze data and interpret results. The group will extend research opportunities to a number undergraduates, as well as to graduate students.
