Higgs Boson parameters at LHC

The search for the Higgs Boson is one of the main goals for the LHC. If a Higgs-like particle is discovered, it is important to determine that it is the Higgs Boson of the Standard Model.In order to establish this, the parameters of the Higgs Boson itself and of the Higgs Mechanism shall be experimentally addressed, most notably its mass, charge, spin and parity as well as its relative and absolute couplings to fermions and bosons, i.e. its partial decay widths. In the talk, the plans for such measurements in ATLAS and CMS are reviewed, based on MC studies
