拓扑大质量规范理论的BRST分析:新观测

BRST analysis of topologically massive gauge theory: novel observations

R. Kumar, R. P. Malik

摘要:

一个动力学非阿贝尔2-形式规范理论(含B \wedge F项)被赋予“标量”和“矢量”规范对称性变换.在我们目前的努力中,我们利用后者的规范对称性变换和执行的4(3 + 1)维(4D)拓扑有质量的非阿贝尔2-形式的规范理论的Becchi-Rouet-Stora-Typhoon(BRST)分析。我们证明了存在一些新的功能,迄今为止,没有观察到的背景下,BRST方法的四维(非)阿贝尔1-形式以及阿贝尔2-形式和3-形式的规范理论。我们评论的“标量”和“矢量”规范对称性的理论的BRST分析中出现的新功能之间的差异。

英文摘要:

A dynamical non-Abelian 2-form gauge theory (with B \wedge F term) is endowed with the "scalar" and "vector" gauge symmetry transformations. In our present endeavor, we exploit the latter gauge symmetry transformations and perform the Becchi-Rouet-Stora-Tyutin (BRST) analysis of the four (3 + 1)-dimensional (4D) topologically massive non-Abelian 2-form gauge theory. We demonstrate the existence of some novel features that have, hitherto, not been observed in the context of BRST approach to 4D (non-)Abelian 1-form as well as Abelian 2-form and 3-form gauge theories. We comment on the differences between the novel features that emerge in the BRST analysis of the "scalar" and "vector" gauge symmetries of the theory.
