Abstract

We present a study of the prospects for the measurement of TeV-scale light-flavored right-squark masses and the corresponding production cross section at a 3 TeV e+e- collider based on CLIC technology. The analysis, performed in the framework of the CLIC Conceptual Design Report, is based on full Geant4 simulations of the CLIC_ILD detector concept, including standard model physics background and machine related hadronic background from two-photon processes. The events are reconstructed using particle flow event reconstruction, and the mass is obtained from a template fit built from generator-level simulations with smearing to parametrize the detector response. For an integrated luminosity of 2/ab, a statistical precision of 5.9 GeV, corresponding to 0.52%, is obtained for unseparated first and second generation right squarks. For the combined cross section, a precision of 0.07 fb, corresponding to 5%, is obtained.
