U.S.-France Cooperative Research: The Electro and Photoproduction of Vector Mesons at Thomas Jefferson National Accelerator Facility

9981623Djali这项为期三年的美法亚原子物理合作奖由Chaden Djalali、David Tedeschi、南卡罗来纳大学的研究生以及巴黎大学奥赛分校核物理研究所的Michel Guida和他的研究小组获得。美国和法国的团队将在托马斯·杰斐逊国家加速器设施中使用CEBAF大接受光谱仪进行实验，以研究矢量介子的电和光产生。核密度对相对论重离子碰撞和矢量介子对核子电产生反应的影响的实验计划在未来三年内进行。这些团队将定期会面，设计实验，进行数据分析，并讨论理论问题。该奖项代表了美方向NSF和法国国家科学研究中心(CNRS)提出的联合建议。NSF将支付美国调查人员和研究生的旅费和生活费，CNRS将支持法国研究人员访问美国。该项目结合了美国研究人员的实验专业知识和法国团队的理论知识，将促进对矢量介子在核反应中的作用以及对核子和原子核结构的理解。

9981623DjalaliThis three-year award for U.S.-France collaboration in subatomic physics involves Chaden Djalali, David Tedeschi, and graduate students at the University of South Carolina and Michel Guidal and his research group at the Institute of Nuclear Physics, University of Paris in Orsay. The U.S. and French teams will conduct experiments using the CEBAF Large Acceptance Spectrometer at the Thomas Jefferson National Accelerator Facility for investigations of electro and photoproduction of vector mesons. Experiments on the effect of nuclear density on relativistic heavy ion collisions and on vector meson electroproduction reaction on the nucleon are scheduled over the next three years. The teams will meet regularly to design the experiments, perform data analysis, and discuss theoretical issues. The award represents the U.S. side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the U.S. investigators and graduate students and the CNRS will support the visits of the French researchers to the United States. The project combines experimental expertise of the U.S. researchers with the theoretical knowledge of the French team and will advance understanding of the role of vector mesons in nuclear reactions and into the structure of the nucleon and nuclei.
