量子引力的规范不变重整化

Gauge invariant renormalizability of quantum gravity

P. M. Lavrov, I. L. Shapiro

AI总结:

本文利用Batalin-Vilkovisky技术和背景场方法,证明了一般微分同胚不变且无额外潜在反常对称性的量子引力模型的规范不变重整化,为协变量子引力中有效作用紫外发散的局部协变性提供了理论支撑。

摘要:

目前对量子引力(QG)中重整化的理解,基于协变QG模型中有效作用的紫外发散是协变局部表达式这一事实。这一基本陈述在QG中起核心作用,因此,在尽可能广泛的QG理论范围内证明它非常重要。使用Batalin-Vilkovisky技术和背景场方法,我们详细阐述了一般量子引力模型的规范不变重整化证明,该模型具有微分同胚不变性且没有额外的潜在反常对称性。

英文摘要:

The current understanding of renormalization in quantum gravity (QG) is based on the fact that UV divergences of effective actions in the covariant QG models are covariant local expressions. This fundamental statement plays a central role in QG and, therefore, it is important to prove it for the widest possible range of the QG theories. Using the Batalin-Vilkovisky technique and the background field method, we elaborate the proof of gauge invariant renormalizability for a generic model of quantum gravity that is diffeomorphism invariant and does not have additional, potentially anomalous, symmetries.
