Precision Electroweak Measurements at Jefferson Lab

该奖项是根据2009年美国复苏和再投资法案资助的（公法111-5）.路易斯安那理工大学粒子物理组（PPG）有一个两部分的实验核物理研究计划，利用位于弗吉尼亚州的托马斯杰斐逊国家加速器设施（TJNAF）的设施，以及一个同伴教育推广计划，旨在让本科生，科学教师，和高中生的前沿物理研究项目。该小组目前的努力集中在TJNAF的宇称违反电子不对称计划，Qweak（E05-008）实验，该实验代表了在非常低的动量转移下的宇称违反测量。 该小组有自己批准的实验（E04-101），该实验在后向角模式下利用G 0仪器测量通道中的奇偶校验违反不对称性，其中数据分析仍在进行中。 这些计划将研究基态核子结构性质，研究QCD对称性破缺的动力学，并提供标准模型的精确检验。 对于Qweak实验，Louisiana Tech集团负责Qweak临界系统的区域1 GEM跟踪系统。路易斯安那理工大学是一所农村大学，没有太多机会接触最先进的基础研究。迄今为止，从NSF获得的资金使该小组能够制定一项有力的研究计划和装备精良的实验室。有了这些设施，该小组已经能够制定一个教育推广计划，有两个部分的推力。第一部分涉及我们实验室的本科生和高中生，他们的能力与研究生很相似。他们有一个项目适合他们的能力，使他们能够获得如何进行研究，这是不是在课堂上教有价值的知识的责任。另一部分旨在让高中教师参与我们的研究项目，让他们更好地了解科学和数学，然后将其转化为学习模块，供他们带回课堂。该提案的资助将使路易斯安那理工大学继续为物理学研究做出重大贡献，并为本科生，当地高中学生和教师提供教育机会，为招收学生进入科学学科提供了一个很好的途径。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The Louisiana Tech Particle Physics Group (PPG) has a two part experimental nuclear physics research program utilizing the facilities at the Thomas Jefferson National Accelerator Facility (TJNAF) located in Virginia and a companion educational Outreach Program designed to involve undergraduate students, science teachers, and high school students in forefront physics research projects. The group's efforts at present are centered on a parity violating electron asymmetry program at TJNAF, the Qweak (E05-008) experiment which represent parity violation measurements at very low momentum transfers. The group had its own approved experiment (E04-101) which utilized the G0 apparatus in the backward angle mode to measure the parity violating asymmetry in the channel where data analysis is still being done. These programs will investigate ground state nucleon structure properties, investigate the dynamics of QCD symmetry breaking, and provide a precision test of the Standard Model. For the Qweak experiment the Louisiana Tech group is responsible for the Region 1 GEM based tracking system for Qweak critical system for the experiment. Louisiana Tech is a rural university with not much opportunity for exposure to fundamental state-of-the-art basic research. The funding thus far received from the NSF has allowed the group to develop a vigorous research program and exceptionally equipped laboratories. With these facilities the group has been able to develop an education outreach program with a two part thrust. The first part involves the undergraduate and the high school students in our labs in a capacity much like that of a graduate student. They have responsibility for a project appropriate to their abilities which allows them to gain valuable knowledge of how to conduct research which is not taught in a classroom. The other part is designed to involve high school teachers in our research projects allowing for them to get a better understanding of the sciences and mathematics which can then be translated into learning modules for them to take back to their classrooms. Funding of this proposal will allow the Louisiana Tech group to continue to make major contributions to physics research, and enhance the educational opportunities for undergraduate students, local high school students and teachers, providing an excellent avenue for recruiting students into scientific disciplines.
