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 …
WebThe WIMP Miracle From a particle physics perspective, the early universe was a high energy place where energy and mass could switch from one form to the other freely as enshrined in Einstein's E = mc 2. Pairs of particles and their antiparticles could come and go. However, as the universe expands, it cools.
