降维在电弱和QCD物质中的应用

Applications of dimensional reduction to electroweak and QCD matter

M. Vepsalainen

摘要:

这篇论文是一篇博士论文的引言部分的一个稍微修改的版本,也包含文章hep-ph/0311268,hep-ph/0510375,hep-ph/0512177和hep-ph/0701250。本文讨论了有限温度场论中的有效场论方法,特别是降维方法。我们首先简要回顾了热场论的形式主义,并展示了降维如何作为静态量的高温极限出现。然后,我们将降维应用于两个不同的问题,即电弱理论的压力和热QCD中介子算符的屏蔽质量,并指出它们的相似之处。我们总结了结果并讨论了它们的有效性,同时将所有细节留给原始研究文章。

英文摘要:

This paper is a slightly modified version of the introductory part of a doctoral dissertation also containing the articles hep-ph/0311268, hep-ph/0510375, hep-ph/0512177 and hep-ph/0701250. The thesis discusses effective field theory methods, in particular dimensional reduction, in the context of finite temperature field theory. We first briefly review the formalism of thermal field theory and show how dimensional reduction emerges as the high-temperature limit for static quantities. Then we apply dimensional reduction to two distinct problems, the pressure of electroweak theory and the screening masses of mesonic operators in hot QCD, and point out the similarities. We summarize the results and discuss their validity, while leaving all details to original research articles.
