Possibility of Chargino Search at LEP II

We study the potential of the LEP200 collider for chargino production and the possibility of the determination of some fundamental SUSY parameters through the relation with this study. Total cross sections for two basic signatures of pair chargino production and for main backgrounds are calculated. The set of kinematic cuts is proposed for the effective background suppression and extraction of the signal. Calculations and the MC simulation performed give the limits on chargino and neutralino masses that could be obtained at LEP200 with $\sqrt s =$ 200 GeV.
