Explicit Symmetry Breaking in Non-Abelian Scalar Theories and One-Loop Renormalization
Lucas Ducastelo de C. C. Lima
Non-Abelian gauge theories coupled to scalar fields are fundamental in particle physics, yet they often face high-energy instabilities. In this work, we start by analyzing the clas…

Covariant One-Loop Corrections from a Non-Covariant Expansion: The Scalar Field Case
Lucas Ducastelo de C. C. Lima, Riccardo Fecchio
We compute the one-loop correction to the non-minimal coupling of a scalar field theory to gravity, induced by a quartic self-interaction. We adopt the non-covariant framework of l…
