A WIMPy Baryogenesis Miracle

Understand

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.
