论文摘要
保形异常和异常引起的有效作用代表了描述对重力作用的半经典贡献的有用和经济方法。我们讨论了由度量和标量场形成背景并以两种标准协变形式制定诱导作用的情况。对低能量的诱导作用的分析揭示了与重新归一化组的现有联系和有效的潜力。使用Pauli-Villars正则化考虑了异常术语的分类扩展到标量背景和歧义性的歧义。
The conformal anomaly and anomaly-induced effective action represent useful and economic ways to describe semiclassical contributions to the action of gravity. We discuss the anomaly in the case when the background is formed by metric and scalar fields and formulate the induced action in two standard covariant forms. The analysis of induced action at low energies reveals existing connection to the renormalization group and effective potential. The classification of anomalous terms is extended to the scalar background and ambiguities in the total derivative terms in the anomaly are considered using Pauli-Villars regularization.
