论文摘要
最近提出了提议在量子场理论中处理差异，\ cite {Horowitz：2022RPP：2022uak}，分母正规化（Den。Reg。）方案来处理量子场理论中的分歧。显示出与维度正则化方案一样简单的结果，并且还通过在现场理论中示出几个示例，与最小的减法方案兼容。在本文中，我们指出了这种正则化方案的一些有趣特征，这些特征是通过重新审视QED真空极化和在此正则化方案中$ h \toγγ$衰减的量规不变性的结果。
Recently \cite{Horowitz:2022rpp,Horowitz:2022uak}, denominator regularisation (Den. Reg.) scheme has been proposed to handle divergences in quantum field theory. It is shown to yield results as simple as in dimensional regularisation scheme and also shown to be compatible with minimal subtraction scheme by taking several examples in field theory. In this article, we point out some interesting features of this regularisation scheme which appear as a consequence of the requirement of gauge invariance by revisiting QED vacuum polarisation and $H\toγγ$ decay in this regularisation scheme.
