Abstract:
The investigation of the dynamics responsible for electroweak symmetry breaking
is one of the prime tasks of experiments at present and future hadron colliders.
Experiments at the Tevatron Proton-Antiproton collider or at the CERN Large Hadron
Collider (LHC) must be capable to discover a Standard Model Higgs boson or Higgs
bosons in extended models.
In this talk, the present status of the search for Higgs bosons -in the Standard
Model and in the minimal supersymmetric extension- at the Tevatron is presented.
In addition, a detailed discussion on the Higgs boson discovery potential at the
LHC is given, based on recent detailed studies of a realistic detector performance
of the ATLAS and CMS experiments. To prove that the Higgs mechanism is at work,
it is important to measure the relevant properties of a possible Higgs boson
resonance, like its mass, spin, couplings to fermions and bosons and its selfcoupling.
It is discussed to what extent these parameters can be determined at the LHC.
