The value related to the wimp miracle
http://export.arxiv.org/pdf/1009.3227 WebAbstract. We present a generic framework, baryomorphosis, which modifies the baryon asymmetry to be naturally of the order of a typical thermal relic WIMP density.We consider a simple scalar-based model to show how this is possible. This model introduces a sector in which a large initial baryon asymmetry is injected into particles ("annihilons"), ϕ B, ^ ϕ B, of …
