- This thesis deals with the determination of the total Higgs decay width at the ILC. We perform a model-independent measurement of the Higgs production cross section through WW-fusion. From this measurement we can extract information on the coupling gHWW of the Higgs boson to W-bosons and determine the total decay width of the Higgs boson. The aim of this study is to estimate the measurement accuracies of the total decay width obtainable at the ILC at ps = 250 GeV. The Standard Model Higgs boson with a mass below 140 GeV is expected to decay predominantly into two b-quarks. By using this decay mode the WW-fusion cross section can be measured to an accuracy between 7:2% and 24:32% for mH = 120 GeV to mH = 140 GeV, assuming 250 fbâ»Â¹ of data. The measurement accuracy of the total Higgs decay width varies between approximately 9:0% and 24:44% in the Higgs mass range under consideration.
