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

Abstract

Charginos $\ddot{I}{‡}_1^{\pm }$ 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 $M_2,\hat{I}¼$ and $\tan {\hat{I}}^2$ by measurements of the total cross section and the spin correlations in $e^{+}{e}^{-}$ annihilation to $\ddot{I}{‡}_1^{+}\ddot{I}{‡}_1^{-}$ chargino pairs.
