U.S.-Australia Cooperative Research: Studies in Non-Perturbative QCD and Hadron Dynamics

该项目的主要美国参与者是肯特州立大学的Peter Tandy教授和阿贡国家实验室的Craig Roberts博士。参与该项目的还有汉普顿大学的Michael Frank博士和肯特州立大学的David Kahana博士，他是美国国家科学基金会支持的博士后助理。澳大利亚的主要参与者是墨尔本大学的Bruce McKellar教授和南澳弗林德斯大学的Reginald Cahill博士。该奖项将为美国参与者在两年内访问澳大利亚同事的实验室提供旅费支持。将进行的合作研究是在量子色动力学（QCD）和量子色动力学建模的非微扰研究领域。实验工作将探讨核动力学中重子-介子自由度和夸克-胶子自由度没有明确区分的问题。解决这些问题的重要工具是强子动力学的有效QCD模型。研究的主题包括通过研究QCD Schwinger-Dyson方程确定夸克传播子的结构，在此基础上建立QCD的协变和约束模型，这些模型中的夸克结构和重子和介子的相互作用，以及这些夸克和夸克-反夸克复合物的电弱耦合和形状因子。博士互访。麦凯勒和卡希尔得到了澳大利亚工业、技术和商业部（DITAC）的支持。

The principal U.S. participants in this project are Prof. Peter Tandy of Kent State University and Dr. Craig Roberts of Argonne National Laboratory. Also associated with the project are Dr. Michael Frank from Hampton University and Dr. David Kahana, an NSF-supported post-doctoral associate at Kent State University. The primary Australian participants are Prof. Bruce McKellar of the University of Melbourne and Dr. Reginald Cahill of the Flinders University of South Australia. This award will provide travel support over a two year period for the American participants to visit the laboratories of the Australian colleagues. The cooperative research to be undertaken is in the area of non-perturbative studies in Quantum Chromodynamics (QCD) and QCD modelling. The experimental work will probe issues in nuclear dynamics that have no clear separation between baryon- meson degrees of freedom and quark-gluon degrees of freedom. Important tools for addressing such issues are effective QCD models of hadron dynamics. The topics to be investigated include the determination of the structure of the quark propagator through study of the QCD Schwinger-Dyson equations, the construction of covariant, confining models of QCD based on these studies, the quark structure and interactions of baryons and mesons in such models and the electroweak couplings and form factors of these quark and quark-antiquark composites. The exchange visits by Drs. McKellar and Cahill are being supported through the Australian Department of Industry, Technology and Commerce (DITAC).
