The seminar reports on ongoing studies of the physics and detectors at a future TeV-scale Compact LInear Collider (CLIC). The results shown are an extraction of the Conceptual Design Report, which is to be presented by the end of this year. The novel accelerating technology creates a train of bunches: 50 times
per second, 312 bunches will cross with no more than 0.5 ns between bunch crossings. As a consequence of the intense bremstrahlung and hadronic background creation, the detectors have to cope with high occupancies. Reading out the 312 crossings in one go in between bunch trains, the interesting physics has to be disentangled from the overlapping background. To this end, the detectors are designed for high granularity particle flow, where reduction of the background relies on the ability to temporally and spatially separate energy depositions of the background from those from the physics interaction of interest. Full simulation and reconstruction analyses have been performed of so-called benchmark channels, to assess the performance of the detectors. The conclusion is that the ability to perform precision physics at the 3 TeV e+e- collider is established.
