Light Higgs Studies for the CLIC CDR

Abstract

The Higgs boson is the most anticipated discovery at the LHC, which can only partially explore its true nature. Thus one of the most compelling arguments to build a future linear collider is to investigate properties of the Higgs boson, especially to test the predicted linear dependence of the branching ratios on the mass of the final state. At a 3TeV CLIC machine the Higgs boson production cross section is relatively large and allows for a precision measurement of the Higgs branching ratio to pairs of b and c quarks, and even to muons. The cross section times branching ratio of the decays $H\to b\bar{b}$, $H\to c\bar{c}$ and $H\to \hat{I}{¼}^{+}\hat{I}{¼}^{-}$ can be measured with a statistical uncertainty of approximately 0.22%, 3.2% and 15%, respectively.
