Measurement of the Cross Section Times Branching Ratio of Light Higgs Decays at CLIC (1202.5647v1)

Abstract: The investigation of the properties of a Higgs boson, especially a test of the predicted linear dependence of the branching ratios on the mass of the final state, is currently one of the most compelling arguments for building a linear collider. We demonstrate that the large Higgs boson production cross section at a 3 TeV CLIC machine allows for a precision measurement of the Higgs branching ratios. The cross section times branching ratio of the decays H \rightarrow b^{-}b, H \rightarrow cc^{-} and H \rightarrow {\mu}{\mu} can be measured with a statistical uncertainty of 0.22%, 3.2% and 15%, respectively.
