Description
We consider the role that gauge symmetry breaking terms play on the continuum limit of gauge theories in three dimensions.
As a paradigmatic example we consider scalar electrodynamics in which $N_f$ complex scalar fields interact with a U(1) gauge field. We discuss under which conditions a mass term destabilizes the critical behavior (continuum limit) of the gauge-invariant theory and the nature of the asymptotic continuum limit observed once the gauge-breaking term is introduced.
