QCD-based Field Theory Modeling of Nuclear Interactions

9414291坦迪：强子物理的理论研究和计算是在一个基于qcd的模型场理论中进行的，该理论适用于当前和未来的核物理问题。具体的主题包括核子的限制夸克凝聚模型，选择的复合夸克-反夸克介子的传播子的脱壳结构，在强子的电磁和轴流中的修饰夸克和介子子结构效应，以及与核力中电荷对称破缺相关的介子混合。这项工作的目的是在夸克-胶子动力学和有效介子-核子动力学之间提供一座桥梁，这将是实验项目所必需的，比如CEBAF的实验项目，在距离尺度上探测强子大小内的核相互作用。＊＊＊

9414291 Tandy Theoretical investigations and calculations in hadron physics are being carried out within a QCD-based model field theory for the non-perturbative regime appropriate to current and future nuclear physics issues. The specific topics being addressed include a confining quark condensate model of the nucleon, off-shell structure of the propagator for selected composite quark- antiquark mesons, dressed quark and meson substructure effects in electromagnetic and axial currents of hadrons, and meson mixing related to charge symmetry breaking in the nuclear force. The work is aimed at providing a bridge between quark-gluon dynamics and effective meson-nucleon dynamics that will be necessary as experimental programs, such those at CEBAF, probe nuclear interactions at a distance scale within the size hadrons. ***
