The Higgs boson is a central part of the electroweak theoryand is crucial to generate masses for fermions and the weak gauge bosons.The goal of this work is to set limits on the mass and the decay width of theHiggs boson. The basis to compute the physical quantities is the path integralwhich is here evaluated by means of Monte Carlo simulations thus allowing forfully non perturbative calculations. A polynomial hybrid Monte Carlo algo-rithm is used to incorporate dynamical fermions.
