Abstract
We present a simulation study of the prospects for the mass measurement of TeV-scale light-flavored right-handed squarks at a 3 TeV e+e- collider based on CLIC technology. In the considered model, these particles decay into their standard-model counterparts and the lightest neutralino, resulting in a signature of two jets plus missing energy. The analysis is based on full GEANT4 simulations of the CLIC_ILD detector concept, including Standard Model physics backgrounds and beam-induced hadronic backgrounds from two-photon processes. The analysis serves as a generic benchmark for the reconstruction of highly energetic jets in events with substantial missing energy. Several jet finding algorithms were evaluated, with the longitudinally invariant kt algorithm showing a high degree of robustness towards beam-induced background while preserving the features typically found in algorithms developed for e+e- collisions. The presented study of the reconstruction of light-flavored squarks shows that for TeV-scale squark masses, sub-percent accuracy on the mass measurement can be achieved at CLIC.

Summary
Future high energy e+e− colliders are precision tools for the discovery and the spectroscopy of new particles expected beyond the Standard Model. One attractive extension of the Standard Model is Supersymmetry [1,2], which predicts a rich spectrum of new particles, one superpartner for each Standard Model particle. These new particles are expected to have masses in the range from about 100 GeV to a few TeV, and may come within reach of modern colliders. While the studies are performed within a concrete SUSY scenario used for the physics benchmark studies in the framework of the CLIC conceptual design report (CDR) [9], they can be taken as a more general indication of the CLIC capabilities for pair-produced high-mass states of the same quantum numbers decaying hadronically into a pair of jets and invisible heavy particles
