Many candidate theories for BSM physics involve Yang-Mills gauge fields coupled to scalars. By considering a 'toy model' of a GUT — an SU(3) gauge theory with a scalar 'Higgs' in the fundamental representation — we give analytical reasons to suspect qualitative discrepancies between the spectrum obtained from the conventional perspective of spontaneous gauge symmetry breaking compared to an approach which explicitly requires nonperturbative gauge invariance. We present lattice spectroscopy results which support this conclusion.
