dc.descriptionThe consequences of CP- and CPT-invariance for production and subsequent decay of Majorana fermions are analytically studied. We derive general symmetry relations for the spin density matrix for production of Majorana fermions by polarized fermion-antifermion annihilation which allow to distinguish Majorana from Dirac fermions. We discuss the influence of the spin correlations on energy and angular distributions of the decay products. Numerical results are shown for the production of neutralinos and charginos with subsequent leptonic decay at a future linear collider with longitudinally polarized beams.
