History of Renormalization Theory

在Schweber教授的指导下，Cao博士正在研究量子场论（QFT）重整化计划的历史，涵盖了从20世纪50年代初到80年代初的时期，即：从戴森和萨拉姆完成重整化理论初始阶段的工作，到温伯格、乔治等人提出有效场论的概念。Drs。Cao和Schweber希望证明，随着对重整化物理学理解的变化，量子场论的整体结构模式和作为基本或现象学框架的地位都得到了新的概念化。从而为正确理解量子场论和基本粒子物理学的历史提供了基础。本研究的重点将放在理解量子场理论、s矩阵理论和高能物理之间相互作用的物理和重整化哲学的进展，以及电弱和强相互作用的标准模型。

Dr. T. Y. Cao, working under the direction of Professor Schweber, is examining the history of the renormalization program in quantum field theory (QFT), covering the period form the early 1950's to the beginning of the 1980's--that is, from the work of Dyson and Salam that completed the initial phase of the renormalization theory to the formulation of the notion of effective field theories by Weinberg, Georgi and others. Drs. Cao and Schweber hope to demonstrate that with the changing understanding of the physics of renormalization came a new conceptualization of quantum field theory, both with respect to its global structural pattern and to its status as a fundamental or phenomenological framework, thereby providing a basis for the proper understanding of the history of quantum field theory and of elementary particle physics. The emphasis in this research will be on the advances in understanding the physics and the philosophy of renormalization in the context of the interplay between quantum field theory, S-matrix theory and high energy physics, and that of the standard model of electroweak and strong interactions.
