Title: Looking for a heavy W-ino lightest supersymmetric particle in collider and dark matter experiments

Abstract

We investigate the phenomenology of a wino lightest superparticle as obtained in anomaly mediated supersymmetry breaking and some string models. The Wilkinson Microwave Anisotropy Probe constraint on the dark matter relic density implies a wino lightest superparticle mass of 2.0-2.3 TeV. We find a viable signature for such a heavy wino at CLIC, operating at its highest center of mass energy of 5 TeV. One also expects a viable monochromatic {gamma}-ray signal from its pair-annihilation at the galactic center at least for cuspy dark matter halo profiles.
