无真空能质量隙

Mass gap without vacuum energy

B. Holdom

摘要:

我们考虑软非局部变形的无质量理论,引入了质量间隙。通过使用一个重整化方案,保留了紫外线软的变形,重整化量的低质量尺寸,如正常质量项,消失通过有限的counterterterms。这同样适用于重整化的宇宙学常数。我们把这一讨论与规范理论联系起来,因为它们也会由于格里波夫副本的影响而受到软非定域变形的影响。这些效果比通常描绘的要柔和。

英文摘要:

We consider soft nonlocal deformations of massless theories that introduce a mass gap. By use of a renormalization scheme that preserves the ultraviolet softness of the deformation, renormalized quantities of low mass dimension, such as normal mass terms, vanish via finite counterterms. The same applies to the renormalized cosmological constant. We connect this discussion to gauge theories, since they are also subject to a soft nonlocal deformation due to the effects of Gribov copies. These effects are softer than usually portrayed.
