阿贝尔2-形式规范理论中BRST对称性的各种形式

Various forms of BRST symmetry in Abelian 2-form gauge theory

Sumit Kumar Rai, Bhabani Prasad Mandal

摘要:

在阿贝尔2-形式规范理论的情况下,我们用Batalin-Fradkin-Vilkovisky方法导出了BRST对称性的各种形式.我们发现,所谓的双BRST对称性不是一个独立的对称性,而是从玻色子和鬼扇区的正则变换得到的BRST对称性的推广。通过对玻色子和鬼扇区的拉格朗日乘子进行一般变换,我们进一步得到了BRST和双BRST对称的新形式。

英文摘要:

We derive the various forms of BRST symmetry using Batalin-Fradkin-Vilkovisky approach in the case of Abelian 2-form gauge theory. We show that the so-called dual BRST symmetry is not an independent symmetry but the generalization of BRST symmetry obtained from the canonical transformation in the bosonic and ghost sector. We further obtain the new forms of both BRST and dual-BRST symmetry by making a general transformation in the Lagrange multipliers of the bosonic and ghost sector of the theory.
