Abstract

We study the neutralino mass spectra and production cross sections at an e⁺e^- linear collider in superstring-inspired E₆ models. These models are characterized by the existence of new neutral gauge bosons and singlet Higgs fields which also lead to an extended neutralino sector compared to the Minimal Supersymmetric Standard Model (MSSM) or the Next-To-Minimal Supersymmetric Standard Model (NMSSM). For different E₆ models we develop scenarios with new light exotic neutralinos which may offer important possibilities to distinguish between the models.
