抄録

One of the benchmark processes for the optimisation of the detector concepts proposed for the International Linear Collider is Chargino and Neutralino pair production in an mSugra scenario where χ ±1 and χ02 are mass degenerate and decay into W±χ01 and Z0χ01, respectively. In this case the separation of both processes in the fully hadronic decay mode is very sensitive to the jet energy resolution and thus to the particle flow performance. The mass resolutions and cross-section uncertainties achievable with the ILD detector concept are studied in full simulation at a center of mass energy of 500 GeV, an integrated luminosity of 500 fb-1 and beam polarisations of P(e +, e-) = (30%,-80%). For the χ± 1 and χ02 pair production cross-sections, statistical precisions of 0.84% and 2.75% are achieved, respectively. The masses of χ±1, χ02 and χ01 can be determined with a statistical precision of 2.9 GeV, 1.7 GeV and 1.0 GeV, respectively.
