RUI-Norfolk State University's Research Participation at Jefferson Lab

诺福克州立大学的核与粒子物理学小组从事强相互作用物理学的实验研究。 我们感兴趣的是测试基本的量子色动力学（QCD）签名。 我们的研究是基于托马斯杰斐逊国家加速器设施（杰斐逊实验室- JLab）。 我们的团队参与了JLab正在进行的12-GeV升级的硬件建设（我们正在参与预簇射量热计的建设），以及以前实验的数据分析。 我们的主要研究中心是光生和电生的介子和研究，通过全分波分析，多粒子的最终状态。 特别是，我们正在对来自两个CLAS和CLAS数据采集运行的数据进行分析，这两个运行都探索了奇异强子的产生和扩展介子光谱。 这些研究将在升级后继续进行，在CLAS 12（12 GeV升级的一部分），使用低动量转移的虚光子（电子以非常小的角度散射）。 我们也是PRIMEX合作的一部分，用于高精度测量中性π介子双光子衰变宽度，该宽度将被扩展到包括升级中的etas和eta-prime通道，以及将搜索标准模型的特殊扩展的重光子搜索实验。通过这个实验计划，NSU教师和本科生将直接参与核物理研究前沿的硬件建设和实验数据分析。 NSU是全国领先的HBCU之一，其主校区交通便利，距离杰斐逊实验室不远。 该项目的一个主要目标是为代表性不足的少数群体提供机会，并加强核物理研究的多样性。

The Nuclear and Particle Physics group at Norfolk State University is engaged in experimental studies on the physics of the strong interactions. We are interested in testing basic quantum chromodynamics (QCD) signatures. Our research is based at the Thomas Jefferson National Accelerator Facility (Jefferson Lab - JLab). Our group is involved in hardware construction for the ongoing 12-GeV upgrade at JLab (we are participating in the construction of a Pre-Shower Calorimeter), and in the data analysis of previous experiments. Our main research centers on the photo- and electro-production of mesons and the study, through full Partial Wave Analysis, of multi-particle final states. In particular, we are working on the analysis of data from two CLAS and CLAS data-taking runs, both exploring the production of exotic hadrons and expanding meson spectroscopy. These studies will continue after the upgrade, at CLAS12 (part of the 12-GeV upgrade), using virtual photons (electron scattering at very small angles) at low momentum transfer. We are also part of the PRIMEX collaboration for high precision measurement of the neutral pion two-photon decay width that will be extended to include the etas and eta-prime channels in the upgrade and the Heavy Photon Search experiment that will search for special extensions of the standard model.Through this experimental program, NSU faculty and undergraduate students will directly participate in the construction of hardware and analysis of data from experiments in the forefront of nuclear physics research. NSU is one of the leading HBCUs in the country and its main campus is conveniently located a short distance from Jefferson Lab. A main objective of this project is to provide opportunities to under-represented minorities and strengthen diversity in nuclear physics research.
