Query: Constraining the Sneutrino Mass in Chargino Production and Decay with
  Polarized Beams   Production 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}.
