Abstract: One of the benchmark processes for the optimisation of the detector conceptsproposed for the International Linear Collider is Chargino and Neutralino pairproduction in an mSugra scenario where Chargino-1 and Neutralino-2 are massdegenerate and decay into W+Neutralino-1 and Z+Neutralino-1, respectively. Inthis case the separation of both processes in the fully hadronic decay mode isvery sensitive to the jet energy resolution and thus to the particle flowperformance. The mass resolutions and cross-section uncertainties achievablewith the ILD detector concept are studied in full simulation at a center ofmass energy of 500 GeV, an integrated luminosity of 500 fb-1 and beampolarisations of Pe+,e- = 30% -80%. For the Chargino-1 and Neutralino-2pair production cross-sections, statistical precisions of 0.84% and 2.75% areachieved, respectively. The masses of Chargino-1, Neutralino-2 and Neutralino-1can be determined with a statistical precision of 2.9 GeV, 1.7 GeV and 1.0 GeV,respectively.
