Neutralino Production with Polarized Beams in Extended Supersymmetric Models
S. Hesselbach, F. Franke, H. Fraas
Abstract
We discuss associated neutralino production e+ e- --> χ01 χ02 with both beams polarized in the MSSM, NMSSM and an E6 model. It is shown that neutralinos with a large singlino component can be produced at a high luminosity linear collider in a broad parameter range. Polarization effects in the extended models are compared over the whole parameter space where the lightest neutralino is mainly a singlino. We explain the complete different behavior of these models in some parameter regions, which may help to identify the respective supersymmetric model.
