Dark matter searches and Colliders

We study the potential of neutralino dark matter searches and SUSY particle production at colliders in the framework of the Minimal Supersymmetric Standard Model. We show the effects of a non universal gluino mass parameter. The future experiments will be a stringent probe of the low energy MSSM and neutralino dark matter scenario. The deeper informations on both supersymmetry and astrophysics hypothesis will be obtained by correlation of the different signals or absence of signal.
