Description

We study a chirally invariant Higgs-Yukawa model on a four dimensional space-time lattice by means of a polynomial Hybrid Monte Carlo algorithm. We show results concerning Higgs boson mass bounds in the presence of a hypothetical fourth quark generation for various quark masses. Furthermore we determine the critical temperature of the model, where a phase transition in the vacuum expectation value of the scalar field takes place.
