Gauge-invariant spectral description of the $U(1)$ Higgs model from local composite operators

David Dudal, Duive Maria van Egmond, Marcelo Santos Guimaraes +4

The spectral properties of a set of local gauge-invariant composite operators are investigated in the $U(1)$ Higgs model quantized in the 't Hooft $R_{\xi }$ gauge. These operators enab…
