* Abstract: The Compact Linear Collider (CLIC) is a proposed TeV -scale high-luminosity electron-positron collider. For an optimal exploitation of its physics potential, CLIC is foreseen to be built and operated in three stages, with centre-of-mass energies ranging from 380 GeV up to 3 TeV. Electron beam polarisation is provided at all energies. The initial energy stage will focus on precision measurements of Higgs-boson and top-quark properties. The subsequent energy stages enhance the reach of many direct and indirect searches for new physics beyond the Standard Model and give access to the Higgs self-coupling. The CLIC accelerator design is based on a two-beam acceleration scheme with normal-conducting acceleration structures reaching 100 MV/m. Following many years of beam simulations, component tests, large-scale system tests and design optimisation, CLIC recently produced a comprehensive overview of its physics case, the accelerator design and the detector to the European strategy process. The talk will provide an overview of the CLIC project and its physics potential.

Higgs Physics at CLIC

* Abstract: The Compact Linear Collider (CLIC) is a mature option for a future electron-positron collider operating at centre-of-mass energies of up to 3 TeV. CLIC is foreseen in a staged approach with three centre-of-mass energy stages currently assumed to be 380 GeV, 1.5 TeV and 3 TeV. This contribution discusses the physics potential of CLIC in the area of Higgs physics based on benchmark analyses using full detector simulation. The initial stage of operation allows study of Higgs production in Higgsstrahlung and WW-fusion, resulting in precise measurements of the production cross sections and the total Higgs-boson decay width. Operation at high energy will provide high-statistics samples of Higgs bosons produced in WW-fusion enabling tight constraints on Higgs couplings and measurement of double Higgs production.
