A few multiplets that can be added to the SM contain a lightest neutral component which is automatically stable and provides allowed DM candidates with a non-standard phenomenology. Thanks to coannihilations, a successful thermal abundance is obtained for well defined DM masses. The best candidate seems to be a image fermion quintuplet with mass 4.4 TeV, accompanied by a charged partner image heavier with life-time image, that manifests at colliders as charged tracks disappearing in image with 97.7% branching ratio. The cross section for usual NC direct DM detection is image where image is a nucleon matrix element. We study prospects for CC direct detection and for indirect detection.
