Nicolas Boulanger, E. D. Skvortsov, Yu. M. Zinoviev

摘要:

在反德西特(AdS)和平坦背景下构造了最简单的混合对称规范场与引力的立方相互作用。非交换立方相互作用在AdS中得到的各种微扰方法,包括弗拉德金-瓦西里耶夫建设,有和没有Stueckelberg领域。具有最大数量的施图克尔伯格场的作用量可以在平坦极限中考虑,而不损失物理自由度。由此产生的相互作用在平坦的空间进行比较,通过反场同调微扰方法获得的顶点的分类。结果表明,规范代数成为阿贝尔在平坦的限制,在相反的情况下,在AdS的全对称规范场。

英文摘要:

Cubic interactions between the simplest mixed-symmetry gauge field and gravity are constructed in anti-de Sitter (AdS) and flat backgrounds. Nonabelian cubic interactions are obtained in AdS following various perturbative methods including the Fradkin-Vasiliev construction, with and without Stueckelberg fields. The action that features the maximal number of Stueckelberg fields can be considered in the flat limit without loss of physical degrees of freedom. The resulting interactions in flat space are compared with a classification of vertices obtained via the antifield cohomological perturbative method. It is shown that the gauge algebra becomes abelian in the flat limit, in contrast to what happens for totally symmetric gauge fields in AdS.
