Abstract: An important task at the International Linear Collider (ILC) will be the precise determination of the Higgs boson couplings. Model-independent precision measurements of the couplings sensitive to possible deviations from Standard Model predictions caused by new physics can be performed.In this study we evaluate the measurement accuracies of the Higgs boson branching fractions to b and c quarks and gluons in ννh final states at a 350 GeV ILC. A full simulation of the ILD detector concept for a 125 GeV Higgs with TDR parameters is used assuming an electron (positron) beam polarization of -80% (+30%). To obtain the cross section times branching ratio, a template log likelihood fit to the flavor likenesses of the events is performed. Using the Missing mass of the event in the fit one can distinguish between the two production processes Higgs Strahlung and WW fusion.The current results of the study are presented and an outlook is given on the ongoing work.
