Scientific paper

The author shows that in a general class of models in which the baryon number of the universe is created by electroweak anomalies, the energy density in dark matter may be related to the energy density in baryons as Ωb/Ωdm = c X (proton mass)/(weak scale), where the number c is order unity and calculable from the anomaly equation. The scenario unambiguously predicts charged and neutral particles with weak scale masses which carry a new conserved quantum number and can be pair produced via the weak interactions.
