摘要：

We study CP odd asymmetries in chargino production e(+) e(-) --> (chi) over tilde (+/-)(1)(chi) over tilde (-/+)(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 roots = 800 GeV and longitudinally polarized beams. (C) 2004 Elsevier B.V. All rights reserved.
