Chargino Pair Production in $e^{+}{e}^{-}$ Collisions

Charginos ${\chi }_1^{\pm }$ are expected to be the lightest observable supersymmetric particles in many supersymmetric models. We present a procedure which will allow to determine the chargino mixing angles and, subsequently, the fundamental SUSY parameters $M_2,\mu$ and $\tan \beta$ by measurements of the total cross section and the spin correlations in $e^{+}{e}^{-}$ annihilation to ${\chi }_1^{+}{\chi }_1^{-}$ chargino pairs.
