Abstract

We study chargino production e⁺ e^- -> chi⁺₁ chi^-₁ and the subsequent leptonic decay chi^-₁→ chi⁰₁ e^- nu_e including the complete spin correlations between production and decay. We work out the advantages of polarizing the e⁺ and e^- beams. We study in detail the polarized cross sections, the angular distribution and the forward--backward asymmetry of the decay electron. They can be used to determine the sneutrino mass m_νe.
