Useful trick to compute correlation functions of composite operators
In general, in gauge field theories, physical observables are represented by gauge-invariant composite operators, such as the electromagnetic current. As we recently demonstrated in the context of the U(1) and SU(2) Higgs models [1–3], correlation functions of gauge-invariant operators exhibit very...
