Local gauge-invariant vector operators in the adjoint Higgs model
Giovani Peruzzo
In this work, we scrutinize local gauge-invariant vector operators of dimension four in the adjoint Higgs model, which are candidates for interpolating fields of the fundam…

Gauge-invariant scalar and vector operators in the Higgs model: Ward identities and renormalization
Giovani Peruzzo
In this work, we investigate the renormalization of the gauge-invariant composite operators proposed in \cite{Dudal:2023jsu} to describe the Higgs model from a g…

Useful trick to compute correlation functions of composite operators
Giovani Peruzzo
In general, in gauge field theories, physical observables are represented by gauge-invariant composite operators, such as the electromagnetic current. As we recently demonstrated i…
