  • Abstract:The luminosity spectrum at linear colliders is the probability distribution function of a pair of colliding electron and positron energies. Its determination is mandatory for many precision measurements in the physics program of those colliders. This presentation shows the extraction of the luminosity spectrum at 380GeV CLIC from Bhabha events using a reweighting fit, including effects of Bhabha scattering, ISR and FSR, and detector resolutions. Systematic effects from an imperfect knowledge of the detector resolutions are also presented. Finally, the uncertainties in the luminosity spectrum reconstruction are propagated to the top mass measurement through radiative events. In all cases the uncertainty from the luminosity spectrum reconstruction is small compared to the statistical and theoretical uncertainties.

  • Abstract: We present the performance of particle flow jet reconstruction in e+e- collisions at the Compact Linear Collider (CLIC). The results are based on fully simulated events using the latest version of the CLICdet model, reconstructed with the new software chain. Jet energy and jet angular resolutions are investigated in di-jet events. The ability of the detector to measure precisely heavy resonance masses in hadronic decay channels is evaluated, using the separation power between Z and W di-jet masses as example. The impact of beam background from gamma gamma to hadrons on the jet performance is discussed for background levels expected at different stages of CLIC.
