Title: A dark force for baryons
Abstract: A fundamental connection between baryons and dark matter may
exist in order to explain the apparent stability of these two types of
matter, as well as the observed similarity of their present-day energy
densities. A unified genesis of baryonic and dark matter can arise
naturally in models where the baryon number is promoted to a local
symmetry. The dark matter candidate in these scenarios is generally
charged under the baryon gauge symmetry and must have a mass around the
GeV scale. I will discuss constraints from B-factories, LEP and the
Tevatron, as well as direct detection bounds.
