U.S.-Germany Cooperative Research: Quark Confinement and Hadronic Processes

0129236 Tandy该奖项支持Peter Tandy和来自肯特州立大学的学生与德国图宾根大学理论物理系的Reinhard Alklane合作。 该项目的重点是强子过程的限制夸克和胶子通过汇集两个目前完全不同的调查路线。 美方在利用戴森-施温格方程进行强子的连续非微扰QCD模拟方面具有专长。 为了有用，这些结果必须以规范扇区戴森-施温格方程的模型解的形式打包，至少对于胶子和幽灵装扮的传播子以及胶子-夸克顶点。 这正是德国集团的专长。 他们最近提出了规范扇区戴森-施温格方程的截断形式的最先进的解决方案，并发现了与夸克禁闭和动力学手征对称性破缺的起源有关的意想不到的行为。 该项目有可能影响夸克胶子等离子体，核天体物理学，早期宇宙宇宙学和强相互作用场论的研究。 工作计划规定研究生广泛参与国际

0129236TandyThis award supports Peter Tandy and students from Kent State University in a collaboration with Reinhard Alkofer of the Department of Theoretical Physics at the University of Tuebingen, Germany. The project focuses on hadronic processes in terms of confined quarks and gluons by bringing together two presently disparate lines of investigation. The US side has expertise in continuum nonperturbative QCD modeling of hadrons using the Dyson-Schwinger equations. To be useful, the results must be packaged in the form of model solutions of the gauge sector Dyson-Schwinger equations for at least the gluon and ghost-dressed propagators and the gluon-quark vertex. This is exactly the expertise of the German group. They have recently produced the most advanced solutions of truncat4ed forms of the gauge sector Dyson-Schwinger equations and have found unexpected behavior that relates to the origin of quark confinement and dynamical chiral symmetry breaking. The project has the potential to impact the search for quark-gluon plasma, nuclear astrophysics, early universe cosmology, and strongly interacting field theory. The work plan provides for extensive participation by graduate students in the international
