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.A discussion on non-perturbative effects on annihilation cross section of TeV scale wino LSP added.
