- Kurzfassung
- A simulation and analysis for the measurement of the Higgs Boson branching ratios BR(H to bb), BR(H to cc) and BR(H to gg) for a Standard Model like light Higgs boson (mH = 120 GeV) at the International Linear Collider (ILC) is presented. The analysis is performed at a centre-of-mass energy of sqrt(s) = 350 GeV and an integrated luminosity of 500 fb^-1. Only the Higgs-strahlung process is taken as the signal process. After the event selection a simultaneous fit ofthe branching ratios is applied. The relative statistical errors obtained for the measurement of sigma*BR(H to X) are 1.0% (X = bb), 12.3% (X = cc), and 8.3% (X = gg). For mH = 140 GeV and an integrated luminosity of 1 ab^-1, the relative errors are 1.8% (X = bb), 27% (X = cc), and 16% (X = gg). The results are compared to previous studies.
