T-odd Correlations in the Decay of Scalar Fermions

Abstract.We define a CP-sensitive asymmetry in the sfermion decays

CP-sensitive observables in \(e^ + e^-\to\tilde\chi^0_i \tilde\chi^0_j\) and neutralino decay into the Z boson

CP violation in chargino production and decay into sneutrino

, based on triple product correlations between the momenta of the outgoing fermions. We study this asymmetry in the MSSM with complex parameters. We show that the asymmetry is sensitive to the phases of the parameters μ and M1. The leading contribution stems from the decay chain

How light can the lightest neutralino be
