Abstract

A Monte-Carlo analysis on production and decay of supersymmetric charginos at a future photon-collider is presented. A photon collider offers the possibility of a direct branching-ratio measurement. In this study, the process gamma,gamma -> chi_1^+,chi_1^- -> W+W-chi_1^0chi_1^0 -> 4-jets,chi_1^0chi_1^0 has been considered for a specific mSUGRA scenario. Various backgrounds and parameterised detector simulation have been included. Depending on the centre-of-mass energy, a statistical error for the directly measurable branching ratio BR(chi}_1^+ ->chi}_1^0 W^+) of up to 3.5% can be reached.
