Universidad de Zaragoza (orcid)0000-0003-3669-6241 Trace anomaly and induced action for a metric-scalar background 2023 Access copy available to the general public Unrestricted 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. info:eu-repo/grantAgreement/ES/DGA-FSE/E21-17R info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095328-B-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.2 2023 PHYSICS, PARTICLES & FIELDS 9 / 31 = 0.29 2023 Q2 T1 1.451 2023 Physics and Astronomy (miscellaneous) 2023 Q1 Engineering (miscellaneous) 2023 Q1 8.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion e Silva, W.
