dc.descriptionIn my diploma thesis I calculate a lower mass bound of the lightest nutralino assuming an additional supernova cooling mechanism. I consider elektron-positron annihilation and nucleon-nucleon bremsstrahlung as cooling processes. These cooling processes must not be too effective because they would destroy the neutrino signal (SN 1987a). From this requirement I derive an upper bound for the emitted energy and as a consequence I get a lower bound for the mass of the lightest neutralino.
