Testing soft electroweak SUSY breaking from neutralino, chargino, and charged Higgs boson pairs production at linear colliders

Abstract

We consider the production of neutralino, chargino, and charged Higgs boson pairs in the MSSM framework at future $e^{+}{e}^{-}$ colliders. We show that, for c.m. energies in the one TeV range and in a ``moderately'' light SUSY scenario, a combined analysis of the slopes of these production cross sections could lead to a strong consistency test involving the soft supersymmetric breaking parameters $M_1$, $M_2$, the Higgsino parameter $\mu$, and $\tan \beta$.
