有质量杨-米尔斯场、平移和非半单规范对称性

Massive Yang-Mills fields, translational and nonsemisimple gauge symmetry

I. V. Kostyakov, V. V. Kuratov

摘要:

内对称半单群的规范场是无质量的,需要特殊的方法来保证其质量。大量机构通常包含非半单群的典型移位变换。证明了在非半单内对称局域化条件下,平移生成元所对应的规范场是有质量的。此外,我们还介绍了著名的模型的非线性推广,与当地的平移对称性,因此,大量的规范场。因此,局域伽利略对称性在一对特殊的标量场上实现,导致了大质量电动力学,而欧几里德群的局域化导致了没有物质场的大质量非阿贝尔理论。我们提出了一个简单的解释Stueckelberg机制。

英文摘要:

Gauge fields of semisimple groups of internal symmetries are massless and require the special techniques for guarantee their mass. Massive mechanisms usually contain transformations of shifts typical to nonsemisimple groups. We show that under the localization of nonsemisimple internal symmetry the gauge fields corresponding to translation generators are massive. In addition, we introduce nonlinear generalizations of well-known models, with local translational symmetry and as a result, the massive gauge fields. Thus, the local Galilean symmetry is realized on a special pair of scalar fields, leading to massive electrodynamics, and the localization of the Euclidean group leads to massive non-Abelian theory without matter fields. We propose a simple interpretation of the Stueckelberg mechanism.
