微扰量子引力的广义BRST对称性和规范形式:新观测

Generalized BRST Symmetry and Gaugeon Formalism for Perturbative Quantum Gravity: Novel Observation

Sudhaker Upadhyay

摘要:

本文着重指出了Einstein弯曲时空中微扰量子引力理论的Yokoyama规范场形式的新特点。在规范形式框架下证明了微扰引力理论的量子规范变换。这些量子规范变换导致重整化规范参数。进一步,我们分析了BRST对称规范形式主义,它嵌入了更可接受的Kugo-Ojima辅助条件。此外,BRST对称性是有限的和场相关的。值得注意的是,在有限和依赖于场的BRST对称性下,路径积分的雅可比算符相当于微扰量子引力有效理论中的精确规范作用量。

英文摘要:

In this paper the novel features of Yokoyama gaugeon formalism are stressed out for the theory of perturbative quantum gravity in Einstein curved spacetime. The quantum gauge transformations for the theory of perturbative gravity are demonstrated in the framework of gaugeon formalism. These quantum gauge transformations lead to renormalized gauge parameter. Further, we analyse the BRST symmetric gaugeon formalism which embeds more acceptable Kugo-Ojima subsidiary condition. Further, the BRST symmetry is made finite and field-dependent. Remarkably, the Jacobian of path integral under finite and field-dependent BRST symmetry amounts to the exact gaugeon action in the effective theory of perturbative quantum gravity.
