渐近展开的Yang-Mills谱action的重整化

Renormalization of the asymptotically expanded Yang-Mills spectral action

Walter D. van Suijlekom

摘要:

我们研究了平坦四维背景流形上Yang-Mills系统谱作用量的重整化性,重点研究了其渐近展开。将后者解释为一个高阶导数的规范理论,一个功率计算的论证表明它是超可重整化的。我们在一个背景场规范中使用zeta函数正则化确定了单圈的反项,并建立了它们的规范不变性。因此,相应的场论可以通过谱作用量中出现的谱函数的简单移位而重整化。这份手稿提供了比较短的配套文件,我们已经使用(正式)量子作用原理,以达到规范不变性的反条款更多的细节。在这里,我们给出了另外一个明确的表达规范传播子和比较最近的结果在文献中。

英文摘要:

We study renormalizability aspects of the spectral action for the Yang-Mills system on a flat 4-dimensional background manifold, focusing on its asymptotic expansion. Interpreting the latter as a higher-derivative gauge theory, a power-counting argument shows that it is superrenormalizable. We determine the counterterms at one-loop using zeta function regularization in a background field gauge and establish their gauge invariance. Consequently, the corresponding field theory can be renormalized by a simple shift of the spectral function appearing in the spectral action. This manuscript provides more details than the shorter companion paper, where we have used a (formal) quantum action principle to arrive at gauge invariance of the counterterms. Here, we give in addition an explicit expression for the gauge propagator and compare to recent results in the literature.
