Axinos Cold Dark Matterand their collider signatures
Axinos are the supersymmetric partners of the axion and are present in any model invoking both the Peccei Quinn mechanism to solve the strong CP problem and supersymmetry. In this talk I will describe the proposal of axinos as Lightest Supersymmetric Particles (LSP) and Cold Dark Matter and show that they can be produced in the Early Universe with the right energy density. I will then discuss consequences for colliders in the framework of the Constrained MSSM and in particular the case of the decay of a stau NLSP.
