论文部分内容阅读
论文的主旨是为从事核结构理论研究的青年物理学家介绍基于手征有效场论的微观核力.论文将侧重解释手征有效场论的基本概念,以达核结构与少体核物理两个研究领域相互交流之目的.我从静电学的多极展开出发,指出有效场论本质是近似理论,是以低、高两个能标之比为小量的泰勒展开,而该例子中体现的power counting(数幂规则)是任何有效场论的基石.接着,Weinberg对手征理论中的费曼图作power counting的一般方法被引入,量子色动力学的手征对称性及其自发破缺对这种power counting方法的成功起到很重要的作用.在剩下的篇幅中,重整化与power counting的关系将是讨论的重点.我将阐述重整化如何帮助我们更好地理解短程核力.
The purpose of the dissertation is to introduce the microscopic nuclear forces based on the chiral effective field theory to the young physicists engaged in the study of nuclear structure theory.The thesis will focus on explaining the basic concepts of chiral effective field theory, A research field of mutual exchange of purpose.From the electrostatic multi-polar start, I pointed out that the effective field theory is the approximation theory, is the low, high two energy standard ratio for a small amount of Taylor expansion, and in this example The power counting rule is the cornerstone of any effective field theory Weinberg then introduces the general method of Feimunt graph for power counting in chiral theory, the chiral symmetry of quantum chromodynamics and its spontaneous breaking For the success of this power counting method plays an important role in the rest of the length, the relationship between renormalization and power counting will be the focus of discussion.I will explain how renormalization can help us to better understand the short-range Nuclear power.
