Non-perturbative investigation of the fermion-Higgs sector of the standard model

Abstract

We present results for the renormalized quartic self-coupling $\lm_R$ and the renormalized Yukawa coupling $y_R$ in a fermion-Higgs model with two SU(2) doublets, indicating that with the standard lattice regulator these couplings cannot become very strong.
