QED的一种简单的5D UV完成方法

A Simple UV-Completion of QED in 5D

Roberto Iengo, Marco Serone

摘要:

我们构造了一个类Lifshitz的五维QED,它是UV完成的,在低能量下约化为普通的五维QED。这个理论的紫外量子行为是非常平滑的。特别地,在微扰理论中,规范耦合常数在所有能量标度和所有阶数下都是有限的。我们研究了这个理论的IR性质,当在一个圆上紧致化时,并比较了Lifshitz理论与标准5D QED有效场论中耦合的单圈能量依赖性。的有效性的范围内的5D有效场论被发现同意更保守的版本的朴素量纲分析。

英文摘要:

We construct a Lifshitz-like version of five-dimensional (5D) QED which is UV - completed and reduces at low energies to ordinary 5D QED. The UV quantum behaviour of this theory is very smooth. In particular, the gauge coupling constant is finite at all energy scales and at all orders in perturbation theory. We study the IR properties of this theory, when compactified on a circle, and compare the one-loop energy dependence of the coupling in the Lifshitz theory with that coming from the standard 5D QED effective field theory. The range of validity of the 5D effective field theory is found to agree with the more conservative version of Naive Dimensional Analysis.
