A Shadow Matter Universe
arXiv:hep-ph/9303252
Abstract
The cosmological and astrophysical implications of a shadow matter model which could also have interesting experimental consequences are examined. The model has identical microphysics for both the ordinary and shadow worlds but requires a macroscopic asymmetry from nucleosynthesis constraints. It is proposed that this macroscopic asymmetry can be generated at the quark-hadron phase transition.
