Supersymmetry Working Group: Summary Report

Abstract

This report summarizes the progress in SUSY studies performed during the Extended ECFA/DESY Workshop since the TESLA TDR. Based on accurate future measurements of masses of SUSY particles and the determination of the couplings and mixing properties of sfermions and gauginos, we discuss how the low-energy Lagrangian parameters can be determined. In a bottom-up approach, by extrapolating to higher energies, we demonstrate how model assumptions on SUSY breaking can be tested. To this end precise knowledge of the SUSY spectrum and the soft SUSY breaking parameters is necessary to reveal the underlying supersymmetric theory.
