This report summarizes a study of the physics potential CLIC e+e- linear collider operating at centre-of-mass energies from 1 TeV to 5 with luminosity order 10^35 cm^-2 s^-1. First, complex is surveyed, emphasis on aspects related its capabilities, particularly and energy, also possible polarization, \gamma\gamma e-e- collisions. The next Test facility, CTF3, R&D programme are reviewed. We then discuss experimentation CLIC, including backgrounds experimental conditions, present conceptual detector design used in analyses, most which use nominal energy 3 TeV. contributions Higgs could include completing profile light boson by measuring rare decays reconstructing potential, or discovering one more heavy bosons, probing CP violation sector. Turning beyond Standard Model, might be able complete supersymmetric spectrum make precise measurements sparticles detected previously LHC lower-energy collider: collisions polarization would useful for these tasks. have unique capabilities other extensions such as theories extra dimensions new vector resonances, contact interactions models strong WW scattering high energies. In all scenarios we studied, provide significant fundamental information that available collider, result combination precision.
