项目摘要

It is well known that protons and neutrons are made from constituents, called quarks and gluons, which give substructure to these particles. The goal of this project is to make measurements of the spatial distributions and the momenta of the quarks that provide a three-dimensional map of quarks in the nuclear medium. This knowledge provides the basis of our understanding of nuclear matter in terms of the dynamics of their internal constituents. Using this information, theoretical models show how the constituent parts of the proton and neutron can be used to build up its fundamental intrinsic properties, i.e. its overall size, or radius, and quantum mechanical spin. This project engages the PI and Duquesne University's undergraduate students in research aiming to study the strange sea using semi-inclusive production of Kaons with CLAS12 at Jefferson Lab. Physics analysis of 6 GeV Kaon data from eg2 experiment and software development projects for 12 GeV experiments will be performed at Duquesne University, while hardware and detector tests will be carried out at Jefferson Lab. The PI is leading the calibrations of a hybrid Ring Imaging CHerenkov (RICH) detector which is currently under construction. This detector will be used for hadron identification in the momentum range of 3 to 8 GeV/c. Undergraduates play an integral part in this project, which provides them with opportunities to further their training and education outside of the classroom. This will include: gaining experience in the design, assembly, and testing of modern particle Physics detectors, high tech fast electronics, and scientific data analysis.

众所周知，质子和中子是由称为夸克和胶子的成分制成的，这些成分为这些颗粒提供了子结构。该项目的目的是对空间分布进行测量和夸克的动量，这些夸克在核培养基中提供了三维夸克图。这些知识为我们对核问题的理解基于其内部成分的动态提供了基础。使用这些信息，理论模型显示了如何使用质子和中子的组成部分来构建其基本的内在特性，即其整体大小或半径或半径以及量子机械旋转。该项目与PI和Duquesne大学的本科生参与研究，旨在使用Jefferson Lab的CLAS12的半精制生产Kaons研究奇怪的海。 EG2实验和软件开发项目的6个GEV KAON数据的物理分析将在Duquesne University进行12个GEV实验，而硬件和探测器测试将在杰斐逊实验室进行。 PI领导着目前正在建设的混合环成像Cherenkov（Rich）检测器的校准。该检测器将用于3至8 GEV/c的动量范围内的强子识别。本科生在该项目中起着不可或缺的作用，这为他们提供了在课堂外进一步培训和教育的机会。这将包括：在现代粒子物理探测器，高科技快速电子设备和科学数据分析的设计，组装和测试方面获得经验。
