CP violation in chargino production and decay into sneutrino

Abstract

We study CP odd asymmetries in chargino production E+ E- --> ~Chi(+-)(1) C̃hi(-+)(2) and the subsequent two-body decay of one chargino into a sneutrino. We show that in the Minimal Supersymmetric Standard Model with complex parameter \mu the asymmetries can reach 30 %. We discuss the feasibility of measuring these asymmetries at a linear collider with \sqrt{s} = 800 GeV and longitudinally polarized beams.
