Abstract: Abstract We consider a chirally invariant lattice Higgs-Yukawa model based on the Neuberger overlap operator $\mathcal{D}^{(ov)}$ . The model will be evaluated using PHMC-simulations and we will present final results on the upper and lower Higgs boson mass bound. The question of a fourth generation of heavy quarks has recently gained attention and we will illustrate preliminary results of the Higgs boson mass bounds within this framework. Finally we will discuss our progress on properties of the Higgs boson with respect to its unstable nature, such as the decay width and the resonance mass of the Higgs boson.
