Constraints on Neutralino masses and mixings from Cosmology and Collider Physics
Ulrich Langenfeld
Bounds on cross section measurements of chargino pair production at LEP yield a bound on the chargino mass. If the GUT relation is assumed, the lightest neutralino must be heavier…

The Role of Beam polarization for Radiative Neutralino Production at the ILC
Herbert K. Dreiner, Olaf Kittel, Ulrich Langenfeld
We analyze the impact of electron and positron beam polarization on radiative neutralino production at the International Linear Collider (ILC). We focus on three different mSUGRA s…

Eine untere Massenschranke fuer Neutralinos aus Supernova-Kuehlung
Ulrich Langenfeld
In 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 nucl…
