Physics performances for Scalar Electrons, Scalar Muons and Scalar Neutrinos searches at CLIC

The determination of scalar leptons and gauginos masses is an important part of the program of spectroscopic studies of Supersymmetry at a high energy linear collider. In this note we present results of a study of the processes: e+e− → e ̃+R e ̃−R → e+e− χ ̃10 χ ̃10, e+e− → μ ̃R+ μ ̃R− → e+e− χ ̃10 χ ̃10, e+e− → e ̃+L e ̃−L → e+ e− χ ̃20 χ ̃20 and e+e− → ν ̃e ν ̃e → e+ e− χ ̃1+ χ ̃1− in a Supersymmetric scenario at 3 TeV at CLIC. We report the expected accuracies on the production cross sections and on the e ̃R, μ ̃R, ν ̃e, χ ̃1± and χ ̃10 mass determination. We present the performances on the lepton energy resolution and boson mass resolution, and discuss the requirements on the luminosity spectrum, boson tagging, as well as on the detector time stamping capability and beam polarization. Results are obtained after full simulation and reconstruction with overlay of beam-beam induced background.
