Mentions: The most direct way to detect -violation is to construct -odd observables which cannot be mimicked by other parameters of the theory. Such quantities typically involve asymmetries constructed as triple products of momenta and/or spin vectors. Due to spin correlations, such asymmetries show unique hints for phases already at tree level. Triple product asymmetries have been proposed in many theoretical papers in which neutralino production with two- and three-body decays, charginos with two- and three-body decays, also with transversely polarised beams, have been studied in the past [1264–1269]. At tree level, the neutralino and chargino sector has two independent phases: for instance of and when rotating away the phase of .
