It has been recently shown that the electroweak baryogenesis mechanism isfeasible in Standard Model extensions containing extra fermions with largeYukawa couplings. We show here that the lightest of these fermionic fields cannaturally be a good candidate for cold dark matter. We find regions in theparameter space where the thermal relic abundance of this particle iscompatible with the dark matter density of the Universe as determined by theWMAP experiment. We study direct and indirect dark matter detection for thismodel and compare with current experimental limits and prospects for upcomingexperiments. We find, contrary to the standard lore, that indirect detectionsearches are more promising than direct detection ones, and they alreadyexclude a portion of the parameter space.Comment: 26 pages, 15 figure
