Abstract

The Schwinger–Dyson equation for the quark self-energy is solved in the quenched ladder approximation for several cases of one- and two-quark generations. The exchanges of standard model gluons and Higgs bosons are taken into account. It is found that Higgs boson exchange dominates the quark self-energy in the uv region for sufficiently large input quark masses (> 75 GeV ), causing the running quark propagator mass to increase with energy scale. The running of the quark mixing angles is also considered. No running of the quark mixing angles is found for input quark masses up to and including 500 GeV.
