A WIMPy Baryogenesis Miracle
  We explore models in which weakly interacting massive particle (WIMP) dark
matter annihilation is directly responsible for baryogenesis, thereby
connecting dark matter with baryogenesis. We call this process "WIMPy
baryogenesis". The dark matter relic density in these models, as with
conventional WIMP models, is obtained with only order one couplings and
TeV-scale masses according to the WIMP miracle. Thus, WIMPy baryogenesis models
naturally accommodate weak-scale dark matter. Furthermore, an extension of the
WIMP miracle simultaneously explains the observed baryon asymmetry and the
correct dark matter abundance. The models we present have the further feature
that they create the baryon number asymmetry at the weak scale, thereby
avoiding the problems in some models of baryogenesis associated with high
reheat temperatures in supersymmetric theories. Some of these models yield
observable consequences in ongoing and future experiments.
