项目摘要
The visible universe is made up of nucleons: protons and neutrons, and electrons. Nucleons themselves are interacting dynamical systems of partons, quarks and gluons, the degrees of freedom of the theory of strong interaction, Quantum Chromo Dynamics (QCD). Unfolding the QCD quark and gluon structure of nucleons is one of the highest priorities of nuclear physics. The main objective of this project is to advance theoretical and phenomenological studies of the three-dimensional (3D) momentum and spin structure of the nucleon in QCD and to map its internal landscape encoded in the Transverse Momentum Dependent parton distribution and fragmentation functions. The PI will contribute to the education of a diverse, globally-engaged workforce with world-class skills by providing and developing courses on modern statistics and nuclear physics, organizing and teaching summer schools for graduate students, and running annual workshops on the 3D structure of the nucleon.The scientific goals of this project are to precisely extract the 3D nucleon structure and Transverse Momentum Dependent distribution and fragmentation functions from the existing experimental data. TMDs are intimately related to the correlations of parton spin and motion with the spin of the nucleon and generate Spin Asymmetries in scattering processes. The project is intended to unify existing formalisms of the description of the 3D nucleon structure, and ultimately explore the origin of the Spin Asymmetries in various processes. The data from past and existing facilities, such as HERMES (DESY), COMPASS (CERN), and Jefferson Lab, BELLE (KEK), BaBar (SLAC), BESIII (Beijing), RHIC (BNL), LHC (CERN), will be used. This study will be performed for constructing the global QCD fit of the data and unifying collinear and TMD physics. The PI will study TMD evolution, extract the non-perturbative input from the experimental data and use it for the description and prediction of future data. This project will expand the impact of the existing programs at Jefferson Lab and Brookhaven National Laboratory, and of the future Electron Ion Collider in the USA by performing phenomenological and theoretical studies, providing analysis, explanation of present data, and predictions for future measurements.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.
可见的宇宙是由核子组成的:质子、中子和电子。核子本身是部分子、夸克和胶子的相互作用动力学系统,强相互作用理论的自由度,量子染色体动力学(QCD)。揭示核子的QCD夸克和胶子结构是核物理的最高优先事项之一。该项目的主要目标是推进QCD中核子的三维(3D)动量和自旋结构的理论和唯象研究,并绘制其内部景观编码的横向动量依赖部分子分布和碎裂函数。PI将通过提供和开发现代统计和核物理课程,组织和教授研究生暑期学校,该项目的科学目标是精确地提取三维核子结构和与横向动量相关的分布和碎裂根据现有的实验数据。TMD与部分子的自旋和运动与核子自旋的关联密切相关,并在散射过程中产生自旋不对称性。该项目旨在统一现有的三维核子结构描述的形式,并最终探索各种过程中自旋不对称性的起源。将使用来自过去和现有设施的数据,如爱马仕(DESY),COMPASS(CERN),杰斐逊实验室,贝儿(KEK),BaBar(SLAC),BESIII(北京),RHIC(BNL),LHC(CERN)。本研究的目的是为了建立数据的整体QCD拟合,统一共线和TMD物理。PI将研究TMD的演变,从实验数据中提取非微扰输入,并将其用于未来数据的描述和预测。该项目将扩大杰斐逊实验室和布鲁克海文国家实验室现有项目的影响,并通过进行现象学和理论研究,提供分析,解释现有数据,该奖项反映了NSF的法定使命,并被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准。
