Journal of High Energy Physics 2011(9): 1109.1029-8479http://nrs.harvard.edu/urn-3:HUL.InstRepos:6895878We present a new paradigm for dark matter in which a dark matter asymmetry is established in the early universe that is then transferred to ordinary matter. We show this scenario can fit naturally into weak scale physics models, with a dark matter candidate mass of this order. We present several natural suppression mechanisms, including bleeding dark matter number density into lepton number, which occurs naturally in models with lepton-violating operators transferring the asymmetry.en-USXogenesisJournal Article2012-01-0610.1007/JHEP09(2011)009
