弯曲时空中规范理论的重整化

On the renormalization of gauge theories in curved space-time

Peter M. Lavrov, Ilya L. Shapiro

摘要:

考虑弯曲时空背景下一般规范理论的重整化问题,主要假设是存在规范不变正则化和同态不变正则化。利用Batalin-Vilkovisky(BV)形式可以证明该理论在量子水平上具有规范不变和同态不变的可重整化性,直到任意阶的环展开。从这一点出发,我们讨论了反项的局部性和构造曲面背景下幂次计数可重正化理论的一般规定。

英文摘要:

We consider the renormalization of general gauge theories on curved space-time background, with the main assumption being the existence of a gauge-invariant and diffeomorphism invariant regularization. Using the Batalin-Vilkovisky (BV) formalism one can show that the theory possesses gauge invariant and diffeomorphism invariant renormalizability at quantum level, up to an arbitrary order of the loop expansion. Starting from this point we discuss the locality of the counterterms and the general prescription for constructing the power-counting renormalizable theories on curved background.
