Gaugino Property Determination in the Fully Hadronic Decay Mode at the ILC — •Madalina Chera1,2, Mikael Berggren1, and Jenny List1 — 1DESY, Notkestraße 85, 22607 Hamburg — 2Universität Hamburg, Inst. f. Exp.-Physik, 22761 Hamburg
The physics programme of the planned International Linear Collider (ILC) comprises very high precision measurements of phenomena beyond the Standard Model. The detector designs for the ILC have been particularly optimised for the concept of particle flow, using a GEANT4 based detector simulation.
In order to benchmark the detector and reconstruction performance, a study case which challenges the particle flow algorithm has been chosen. Gaugino pair production in a scenario where the χ1± and χ20 decay into W±χ10 and Z0χ10, respectively, is dominated by the hadronic decays of the gauge bosons. In order to separate the two processes, the jet energy resolution has to be excellent: the ZZ (+ missing energy) events must be distinguishable from the WW (+ missing energy) events. The obtained resolutions on the gaugino masses and polarised cross-sections will be presented for different levels of realism in the detector simulation.
