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正在从事强相互作用物理的实验研究。我们对测试基本量子色动力学(QCD)签名很感兴趣。我们的研究是在托马斯·杰斐逊国家加速器设施(杰斐逊实验室-JLab)进行的。我们团队参与了JLab正在进行的12GeV升级的硬件建设(我们正在参与建造一个淋浴前热量计)，并参与了以前实验的数据分析。我们的主要研究集中在介子的光和电产生，以及通过全分波分析研究多粒子终态。特别是，我们正在对两个类和类数据采集运行的数据进行分析，这两个类都探索了奇异强子的产生，并扩展了介子光谱。这些研究将在升级后在CLAS12(12GeV升级的一部分)上继续进行，使用低动量转移的虚光子(电子在非常小角度上的散射)。我们也是PrimeX高精度测量中性介子双光子衰变宽度的合作的一部分，该合作将扩展到升级中的ETA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的教职员工和本科生将直接参与到核物理研究的前沿实验的硬件建设和数据分析中。南加州州立大学是全国领先的HBCU之一，其主校区距离杰斐逊实验室很近。该项目的一个主要目标是向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.
