Flavour Tagging at CLIC

We present the performance of the LCFI flavour tagging package in a realistic CLIC environment. The application is demonstrated on the examples of the measurement of the cross section times branching ratio of light Higgs decays to b and c quarks at 3 TeV, a study of heavy Higgs decays at 3 TeV and of top pair production at 500 GeV. All studies are based on full detector simulation with a realistic account of the machine- induced background at CLIC.
