The Louisiana Tech Particle Physics Group (PPG) has a two part experimental nuclear physics research program with the main thrust being parity violating electron scattering studies and a companion educational Outreach Program designed to involve undergraduate students, science teachers, and high school students in forefront physics research projects. The groups efforts at present are centered two parity violating electron asymmetry programs at Jefferson Lab, the G0 (E04-115) and Qweak (E05-008) experiments which represent parity violation measurements at relatively high and very low momentum transfers. The group has its own approved experiment (E04-101) utilizing the G0 apparatus in the backward angle mode to measure the parity violating asymmetry in the channel. These three programs will investigate ground state nucleon structure properties, investigate the dynamics of QCD symmetry breaking, and provide a precision test of the Standard Model. The Louisiana Tech group is responsible for the CED-FPD electronics for G0 and the Region 1 GEM based tracking system for Qweak, both critical systems for the experiments. The group will be responsible for the data taking and the analysis for transition measurement.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.

路易斯安那州技术粒子物理小组(PPG)有一个由两部分组成的实验核物理研究计划，主要内容是宇称违反电子散射研究，以及一个旨在让本科生、科学教师和高中生参与前沿物理研究项目的同伴教育推广计划。该小组目前的工作集中在杰斐逊实验室的两个宇称破坏电子不对称计划，G0(E04-115)和QWARE(E05-008)实验，这两个实验代表了在相对较高和非常低的动量转移下的宇称破坏测量。该小组有自己批准的实验(E04-101)，利用G0仪器在后角模式下测量通道中的奇偶破坏不对称性。这三个程序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度测试。路易斯安那州技术小组负责G0的CED-FPD电子设备和QWeak的基于区域1宝石的跟踪系统，这两个系统都是实验的关键系统。该小组将负责数据获取和过渡测量的分析。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。到目前为止，从NSF获得的资金使该组织能够开发出一个强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分两部分推进的教育推广计划。第一部分涉及我们实验室的本科生和高中生，他们的身份很像研究生。他们负责一个适合他们能力的项目，使他们能够获得如何进行研究的宝贵知识，这是课堂上没有教授的。另一部分旨在让高中教师参与我们的研究项目，使他们能够更好地理解科学和数学，然后将其转化为学习模块，供他们带回课堂。这项提案的资助将使路易斯安那理工大学集团继续为物理研究做出重大贡献，并增加本科生、当地高中生和教师的教育机会，为招收学生进入科学学科提供良好的途径。
