费米子有效作用量的普适性和模糊性

Universality and ambiguity in fermionic effective actions

Guilherme de Berredo-Peixoto, Dante D. Pereira, Ilya L. Shapiro

摘要:

讨论了大质量费米子理论中大质量场单圈有效作用量的一个不确定性。对数紫外发散在不同时空维度上的普适性导致了有效作用量有限部分的非普适性,即非定域乘性反常。这种现象存在的一般准则制定和应用到不同的外场费米子运营商。

英文摘要:

We discuss an ambiguity in the one-loop effective action of massive fields which takes place in massive fermionic theories. The universality of logarithmic UV divergences in different space-time dimensions leads to the non-universality of the finite part of effective action, which can be called the non-local multiplicative anomaly. The general criteria of existence of this phenomena are formulated and applied to fermionic operators with different external fields.
