dc.descriptionProduction and decay of gaugino-like charginos are crucially determined by sneutrino exchange. Therefore we study the pair production of charginos e^+ e^- -> chi^+_1 chi^-_1 with polarized beams and the subsequent decay chi^-_1 -> chi^0_1 e^- nu_e, including the complete spin correlations between production and decay. The spin correlations have strong influence on the decay angular distribution and on the corresponding forward-backward asymmetry. We show for two representative scenarios for sqrt{s}=270 GeV and for sqrt{s}=500 GeV that forward-backward asymmetries for polarized beams are an important tool for constraining the sneutrino mass m_{tilde{nu}_e}.
