CP violation in chargino production and decay into sneutrino
Abstract
We study CP odd asymmetries in chargino production E+ E- --> ~Chi(+-)(1) \~Chi(-+)(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 μ the asymmetries can reach 30 %. We discuss the feasibility of measuring these asymmetries at a linear collider with s = 800 GeV and longitudinally polarized beams.
