Can the Couplings in the Fermion-Higgs Sector of the Standard Model be Strong?

Wolfgang Bock, Christoph Frick, Jan Smit +1

We present results for the renormalized quartic self-coupling $λ_{R}$ and the Yukawa coupling $y_{R}$ in a lattice fermion-Higgs model with two SU(2) $_{L}$ doublets, mostly for large val…

Gauge fixing and Gribov copies in pure Yang-Mills on a circle

James E. Hetrick

%In order to understand how gauge fixing can be affected on the %lattice, we first study a simple model of pure Yang-mills theory on a %cylindrical spacetime [ $S U (N)$ on $S^1 \time…

Chiral fermions in two dimensions?

Wolfgang Bock, Asit K. De, Erich Focht +1

Quenched studies of a global U(1) symmetric Wilson-Yukawa model in two dimensions show no evidence of a charged fermion in the vortex phase at strong Wilson-Yukawa coupling while t…

No strong coupling regime in the fermion-Higgs sector of the standard model

Wolfgang Bock, Christoph Frick, Jan Smit +1

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 t…

Staggered fermion approach to chiral gauge theories on the lattice

W. Bock, J. Smit, J. C. Vink

The staggered fermion approach to build models with chiral fermions is briefly reviewed. The method is tested in a U(1) model with axial vector coupling in two and four dimensions.

Fermion-Higgs model with strong Wilson-Yukawa coupling in two dimensions

Wolfgang Bock, Asit K. De, Erich Focht +1

The fermion mass spectrum is studied in the quenched approximation in the strong coupling vortex phase (VXS) of a globally U(1) $_{L} \otimes$ U(1) $_{R}$ symmetric scalar-fermion model i…
