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

Abstract

Charginos $χ_1^\pm$ 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 $M_2, μ$ and $\tanβ$ by measurements of the total cross section and the spin correlations in $e^+e^-$ annihilation to $χ_1^+ χ_1^-$ chargino pairs.
