I will discuss asymmetric dark matter, i.e. dark matter whose relic density is not of thermal origin but due to the dark matter sharing an asymmetry with the baryons, from strong dynamics Two mass scales, the electroweak scale and the few GeV scale are natural for such dark matter to get the right relic density: In the first case dark matter naturally arises as TIMPs (Techni-Interacting Massive Particles) in simple Technicolor models of electroweak symmetry breaking. Some of these can have masses of order 100 GeV with interesting phenomenology in recoil experiments and at LHC. In the latter case few GeV dark matter could arise from hidden strongly interacting sectors and could be captured in the sun at a sufficient rate to affect low energy neutrino fluxes and helioseismology and this scenario could be tested by future neutrino experiments.
