超酉算子与非阿贝尔二型的BRST变换

Superunitary operator and BRST transformations for non-Abelian two-form

Dheeraj Shukla, Kuldeep Kumar

摘要:

利用超空间幺正算符形式,我们导出了非阿贝尔2-形式规范理论的各种(反)BRST对称变换。我们引入了一种新的拉格朗日量,它不仅与1-形式背景场耦合,而且与2-形式背景场耦合。此外,两个规范场也相互耦合。引入了一种新的涉及2-形式规范场的协变导数。我们还提出了一个猜想,把这个想法推广到任何p-形式的规范理论。

英文摘要:

Using superspace unitary operator formalism, we derive various (anti-)BRST symmetry transformations explicitly for the non-Abelian 2-form gauge theories. We introduce a new Lagrangian with a coupling of matter fields not only with 1-from background field but also with a 2-form field. Moreover, the two gauge fields couple mutually as well. A new covariant derivative involving the 2-form gauge field is introduced. We also put forth a conjecture to generalise this idea to any p-form gauge theory.
