  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 (BSM) and give access to the Higgs
self-coupling. Higgs and top-quark projections have been evaluated using full
detector simulation studies. Many new phenomenology studies have been
undertaken to explore the BSM reach of CLIC, from Effective Field Theory (EFT)
interpretations of precision measurements through to signature-based searches;
these include flavour dynamics, and dark matter and heavy neutrino searches.
Selected results that demonstrate the outstanding potential of CLIC in many
physics domains are reviewed.
