IR/UV mixing from local similarity maps of scalar non-Hermitian field theories

Abstract: Pseudo-Hermitian field theories possess a global continuous "similarity" symmetry, interconnecting the theories with the same physical particle content and an identical mass spectrum. In their regimes with real spectra, within this family of similarity transformations, there is a map from the non-Hermitian theory to its Hermitian similarity partner. We promote the similarity transformation to a local symmetry, which requires the introduction of a new vector similarity field as a connection in the similarity sp… Show more
