短距离非微扰物理学

Nonperturbative physics at short distances

V. I. Zakharov

摘要:

在格点量子色动力学中有越来越多的证据表明,试图在真空位形中定位限制场的结果明显依赖于格点间距(即紫外截止)。一般来说,一个处理低维真空缺陷占据了总四维空间的消失分数。我们简要回顾现有的数据上的真空缺陷和它们的意义的限制和其他非微扰现象。我们引入缺陷的“量子数”的概念,并得出一个类比,而正式的一个,发生在大约50年前的发展,并引发了创建的酒田模型。

英文摘要:

There is accumulating evidence in lattice QCD that attempts to locate confining fields in vacuum configurations bring results explicitly depending on tha lattice spacing (that is, ultraviolet cut off). Generically, one deals with low-dimensional vacuum defects which occupy a vanishing fraction of the total four-dimensional space. We review briefly existing data on the vacuum defects and their significance for confinement and other nonperturbative phenomena. We introduce the notion of `quantum numbers' of the defects and draw an analogy, rather formal one, to developments which took place about 50 years ago and were triggered by creation of the Sakata model.
