  • Abstract: High energy $e^+e^-$ colliders such as the Compact Linear Collider (CLIC) or the International Linear Collider (ILC) are very promising future projects for complementing and extending the LHC physics reach. At these colliders, many interesting physics processes will produce multi-jet final states which can be accompanied by charged leptons and missing momentum. High precision measurements at these colliders pose stringent requirements on the detector performance, in particular on the jet energy resolution ($sigma_E/E<3.5\%$ for 100\,GeV--1\,TeV jets). The Particle Flow approach to calorimetry shows potential to meet the unprecedented demands on the jet energy resolution. It is based on highly granular calorimeters and particle flow analysis, i.e. resolving energy depositions of individual particles by sophisticated algorithms. Over the last decade, particle flow calorimetry was explored by the detector R&D collaborations of the future linear colliders, who built and tested large scale high-granularity calorimeter prototypes and studied the detector and software performance in full detector simulations. This talk describes the principles of particle flow analysis and discusses the advancements in particle flow calorimetry. Recent prototype developments of the CALICE collaboration and results from beam tests and full physics simulations are presented with emphasis on the CLIC physics programme.
