000171272 520__ $$aOne of the challenging tasks at future experiments is the clear identification of the underlying new physics model. In this study we concentrate on the distinction between different supersymmetric models, the MSSM and the NMSSM, exploring the gaugino/higgsino sector as an alternative to the Higgs sector. Under the assumption that only the light chargino and neutralino masses and polarized cross sections $e^+e^-\to \tilde{\chi}^0_i\tilde{\chi}^0_j$, $\tilde{\chi}^+_i\tilde{\chi}^-_j$ have been measured, we perform a fit of the fundamental MSSM parameters $M_1$, $M_2$, $\mu$ and $\tan\beta$ and study whether a model distinction is possible. We focus here on the challenging cases of scenarios with a relatively heavy singlino and address two classes of neutralino mixing, $\tilde{\chi}^0_1\sim$higgsino-like versus $\tilde{\chi}^0_1\sim$gaugino-like.
