摘要：
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) over tilde (+)(1)(chi) over tilde (-)(1) -> W+W-(chi) over tilde (0)(1)(chi) over tilde (0)(1) -> q (q) over barq (q) over bar(chi) over tilde (0)(1)(chi) over tilde (0)(1) has been considered for a specific mSUGRA scenario. Various backgrounds and a parameterised detector simulation have been included. Depending on the centre-of-mass energy, a statistical error for the directly measurable branching ratio BR((chi) over tilde (+/-)(1) -> (chi) over tilde W-0(1)+/-) of up to 3.5% can be reached.
