微扰量子引力中的格林函数

Green's Functions in Perturbative Quantum Gravity

Sudhaker Upadhyay, Bhabani Prasad Mandal

摘要:

我们证明了微扰量子引力理论中非线性规范下的格林函数可以用线性规范下的格林函数表示。这个公式也适用于算子格林函数。进一步导出了任意规范对中微扰量子引力理论中格林函数之间的显式关系。这个过程涉及到某种修改的FFBRST变换,它是从无穷小场相关的BRST变换推导出来的。

英文摘要:

We show that the Green's functions in non-linear gauge in the theory of perturbative quantum gravity is expressed as a series in terms of those in linear gauges. This formulation is also holds for operator Green's functions. We further derive the explicit relation between the Green's functions in the theory of perturbative quantum gravity in a pair of arbitary gauges. This process involves some sort of modified FFBRST transformations which is derivable from infinitesimal field-dependent BRST transformations.
