Findings

Preliminary lower Higgs mass bounds at various cutoffs.

Methodology for studying Higgs mass dependence on model parameters.

Outline of future work on upper Higgs mass bounds.

Abstract

We study the parameter dependence of the Higgs mass in a chirally invariant lattice Higgs-Yukawa model emulating the same Higgs-fermion coupling structure as in the Higgs sector of the electroweak Standard Model. Eventually, the aim is to establish upper and lower Higgs mass bounds. Here we present our preliminary results on the lower Higgs mass bound at several selected values for the cutoff and give a brief outlook towards the upper Higgs mass bound.
