Parity Violating Electron Scattering Measurements at Jefferson Lab

路易斯安那理工大学粒子物理组（PPG）的研究计划的主要目标是宇称违反电子散射，该计划将挑战我们对核子结构的理解，探测QCD对称性破缺的动力学，并提供标准模型的精确测试。四个宇称违反电子散射计划在托马斯杰斐逊国家加速器设施（TJNAF），G 0，Qweak，PVDIS和未来的穆勒测量后，12 GeV的TJNAF升级，代表宇称违反测量涵盖了广泛的动量转移从0.03 - 2.0（GeV/c）的平方。 这些测量将研究基态核子性质和核子在向激发态过渡期间的性质，提供标准模型的精确测试，并将弱夸克耦合限制到前所未有的水平。 这些实验中的每一个都对独特而有趣的物理学敏感，并共同构成了一个奇偶违反实验计划，其中路易斯安那理工大学PPG小组发挥了关键作用。 该奖项将使LaTech PPG集团继续为物理研究做出重大贡献，将技术从基础科学转移到工程应用，并提高本科生，当地高中学生和教师的教育机会，为招收学生进入科学学科提供了一个很好的途径。

The main thrust of the research program of the Louisiana Tech (LaTech) Particle Physics Group (PPG) involves parity violating electron scattering, a program of which will challenge our understanding of nucleon structure, probe the dynamics of QCD symmetry breaking, and provide precision tests of the Standard Model. Four parity violating electron scattering programs at Thomas Jefferson National Accelerator Facility (TJNAF), the G0, Qweak, PVDIS and a future Moller measurement after the 12 GeV TJNAF upgrade, represent parity violation measurements covering a broad range of momentum transfers from 0.03 - 2.0 (GeV/c) squared. These measurements will investigate ground state nucleon properties and properties of the nucleon during its transition to excited states, provide precision tests of the Standard Model, and constrain weak quark couplings to unprecedented levels. Each of these experiments is sensitive to unique and interesting physics, and together constitute a program of parity violation experiments in which the Louisiana Tech PPG group plays a critical role. This award will allow the LaTech PPG group to continue to make major contributions to physics research, transfer technology from basic science to engineering applications, and enhance the educational opportunities for undergraduate students, local high school students and teachers, providing an excellent avenue for recruiting students into scientific disciplines.
