Abstract

The Compact Linear Collider (CLIC) is an option for a future electron-positron collider operating at centre-of-mass energies from a few hundred GeV up to 3 TeV. The search for phenomena beyond the Standard Model through direct observation of new particles and precision measurements is one of the main motivations for the high-energy stages of CLIC. An overview of physics benchmark studies assuming different new physics scenarios is given in this contribution. These studies are based on full detector simulations.
New particles can be discovered in most of the considered scenarios almost up to the kinematic limit ($ \sqrt{s} / 2$ for pair production).
The low background conditions at CLIC provide extended discovery potential compared to hadron colliders, for example in the case of non-coloured TeV-scale SUSY particles. In addition to direct particle searches, BSM models can be probed up to scales of tens of TeV through precision measurements. Examples, including recent results on the reaction $e^+e^-\to\gamma\gamma$, are given. Beam polarisation allows to constrain the underlying theory further in many cases. The discussion of LHC results relevant for the CLIC physics case is also included.
