Description

The measurement of the Higgs boson properties at the future e+e− collider can be achieved through the Higgs-strahlung process. Analysis considering leptonic channels have been addressed but they might be statistically limited due to small branching ratios. This analysis extends the studies to full hadronic decays which represent a large branching ratios of about 70%. It also comes with great challenges since the jet clustering may create confusion and the assignment of jets to Higgs and Z comes with ambiguities. In this presentation ZH to full hadronic final state analysis using the state of the art jet tagger algorithm will be presented along with results for the precision that can be achieved. Moreover the combined fit results for the Z->inv. And the full hadronic will be shown.
