Field redefinitions in effective theories at higher orders Criado, Juan Carlos López Pérez, María Victoria Effective Field Theories Beyond Standard Model The invariance of physical observables under redefinitions of the quantum fields is a well-known and important property of quantum field theory. We study perturbative field redefinitions in effective theories, paying special attention to higher-order effects and their impact on matching to an ultraviolet theory at the classical and quantum levels. 2020-04-23T11:50:53Z 2020-04-23T11:50:53Z 2019-03-07 info:eu-repo/semantics/article Criado, J.
