项目摘要
The research program of the James Madison University Particle and Nuclear Physics Group (JMU--PNP) is focused on developing an accurate, 3D picture of the nucleon and on measuring fundamental quantities essential to our understanding of the subatomic world such as the charge radius of the proton and the anomalous muon magnetic moment. The latter holds the promise of probing physics beyond the Standard Model. Given the minuscule size of the nucleon, roughly a millionth of a billionth of a meter, these are not trivial tasks, as they require custom-built detectors, innovative techniques, and in-house developed software. The JMU-PNP group has a long record of excellence in these areas. Through immersion in this state-of-the-art research in intermediate energy nuclear physics, the PIs offer an outstanding educational experience for undergraduate students. Developing solutions for the hardware, software, and big data challenges associated with this research constitute great teaching tools in the formation of undergraduate students, promoting science and educating beyond the university. JMU-PNP group members have a robust presence at Jefferson Lab (experiments in Hall A, B, and C). For the duration of this award the group’s activities aimed at completing the 3D picture of the nucleon include Machine Learning-based structure function and generalized parton distribution studies, and the study of open strangeness production and hadron formation mechanisms (experiment E12-06-117 in Hall B, with group members among the spokespeople). As part of the effort of solving the “proton charge radius puzzle”, the group has joined the PRad-II collaboration, and a group member plays a key role in the effort to secure funding for building this detector. To support future nuclear physics experiments JMU-PNP research will continue to have a strong hardware and software development component. This includes assemble and test the JMU-designed voltage dividers for the SBS ECAL calorimeter; procure and characterize the PMTs for the PRad-II calorimeter and perform long-overdue maintenance and modernization work on several software packages (simulation, charge symmetric background, radiative corrections) essential in the data analysis workflow. The group will also maintain a significant presence in the Fermilab g-2 experiment, which holds the promise of uncovering physics Beyond the Standard Model.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
詹姆斯麦迪逊大学粒子与核物理小组(JMU- PNP)的研究项目专注于开发一个精确的核子3D图像,并测量对我们理解亚原子世界至关重要的基本量,如质子的电荷半径和异常μ子磁矩。后者有望探索超越标准模型的物理学。考虑到核子的尺寸很小,大约是一米的十亿分之一的百万分之一,这些都不是微不足道的任务,因为它们需要定制的探测器,创新的技术和内部开发的软件。JMU-PNP集团在这些领域有着长期的卓越记录。通过沉浸在这个最先进的研究在中间能量核物理,pi提供了一个优秀的教育经验,为本科生。为与本研究相关的硬件、软件和大数据挑战开发解决方案,构成了培养本科生的重要教学工具,促进了大学以外的科学和教育。JMU-PNP小组成员在杰斐逊实验室(实验在大厅a, B和C)有很强的影响力。在本次获奖期间,该小组旨在完成核子三维图像的活动包括基于机器学习的结构函数和广义部分子分布研究,以及开放奇异性产生和强子形成机制的研究(实验E12-06-117在B厅,小组成员为发言人)。作为解决“质子电荷半径难题”努力的一部分,该小组已经加入了PRad-II合作,并且小组成员在确保建造该探测器的资金方面发挥了关键作用。为了支持未来的核物理实验,JMU-PNP研究将继续拥有强大的硬件和软件开发组件。这包括为SBS ECAL量热计组装和测试jmu设计的分压器;采购和表征PRad-II量热计的pmt,并对数据分析工作流程中必不可少的几个软件包(模拟,电荷对称背景,辐射校正)进行长期维护和现代化工作。该小组还将在费米实验室g-2实验中保持重要的存在,该实验有望揭示超越标准模型的物理学。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
