Abstract: (Elsevier)

The effect of electroweak fermion number violation in the early universe is to distribute a fermion number excess over all the electroweak doublets. If baryogenesis is due to physics above the weak scale, this can result in the production of heavy stable particles in numbers comparable to the number of baryons. In particular, there may be enough stable technibaryons present today to account for the missing mass of the universe.
