  The Higgs boson is a central part of the electroweak theory and is crucial to
generate masses for quarks, leptons and the weak gauge bosons. We use a
4-dimensional Euclidean lattice formulation of the Higgs-Yukawa sector of the
electroweak model to compute physical quantities in the path integral approach
which is evaluated by means of Monte Carlo simulations thus allowing for fully
non perturbative calculations. The chiral symmetry of the model is incorporated
by using the Neuberger overlap Dirac operator. The here considered Higgs-Yukawa
model does not involve the weak gauge bosons and furthermore, only a degenerate
doublet of top- and bottom quarks are incorporated. The goal of this work is to
study the resonance properties of the Higgs boson and its sensitivity to the
strength of the quartic self coupling.
