Potential and challenges of the physics measurements with very forward detectors at linear colliders
MetadataShow full item record
The instrumentation of the very forward region of a detector at a future linear collider (ILC, CLIC) is briefly reviewed. The status of the FCAL R and D activity is given with emphasis on physics and technological challenges. The current status of studies on absolute luminosity measurement, luminosity spectrum reconstruction and high-energy electron identification with the forward calorimeters is given. The impact of FCAL measurements on physics studies is illustrated with an example of the sigma(HWW).BR(H - GT mu(+)mu(-)) measurement at 1.4 TeV CLIC.
