Abstract

We investigate the ground state spectrum of a dynamical scalar-fermion-gauge system with an SU(2) gauge group, a scalar doublet, and two degenerate generations of vectorial fermions under the influence of the Brout-Englert-Higgs effect. To this end, we employ lattice methods using the HiRep code. We study the dependence of the system on the (bare) fermion mass and find that the spectrum remains unaffected, up to trivial fermion mass effects. The results are in line with a weakly coupled theory exhibiting the Fröhlich-Morchio-Strocchi mechanism.
