13:30 → 14:30 Renormalization Group Equations of a General Effective Gauge Theory: Bosonic Sector

A general Effective Field Theory (EFT) containing scalars and vectors up to mass dimension six is presented. For such a general theory the complete set of one-loop renormalization group equations (RGEs) is discussed, employing both on-shell unitarity-based and geometric techniques.
The results broadly apply to any EFT with arbitrary gauge symmetry and bosonic degrees of freedom. To illustrate the utility of these results, I will present new results for the running of models containing axion-like particles with CP-violating interactions.
