Looking for a heavy wino LSP in collider and dark matter experiments

Abstract
We investigate the phenomenology of a wino LSP as obtained in AMSB and some string models. The WMAP constraint on the DM relic density implies a wino LSP mass of 2.0-2.3 TeV. We find a viable signature for such a heavy wino at CLIC, operating at its highest CM energy of 5 TeV. One also expects a viable monochromatic γ-ray signal from its pair-annihilation at the galactic centre at least for cuspy DM halo profiles.
