Higgs Boson Mass Bounds from a Chirally Invariant Lattice Higgs-Yukawa Model

  • Philipp Gerhold

We consider a chirally invariant lattice Higgs-Yukawa model based on the Neuberger overlap operator Open image in new window . The model will be evaluated using PHMC-simulations and we will present final results on the upper and lower Higgs boson mass bounds. The question of a fourth generation of heavy quarks has recently gained attention and we will illustrate the effect of heavy quarks on the Higgs boson mass bounds. Finally we report on the unstable nature of the Higgs boson. The resonance mass and width have been computed in a genuinely non-perturbative manner. The results are compared to the former Higgs boson mass bounds.
