Luminogenesis from Inflationary Dark Matter

Abstract

A cosmological model is introduced in which dark matter plays a dominant role throughout the history of the universe, and is the only matter present for temperatures T T15 109 GeV. The gauge group is SU(3) × SU(6)DM × U(1)Y and unifies in such a way that luminous matter is generated at T T15 with the correct amount and eventual asymmetry. Construction of more highly sensitive direct detectors of dark matter (e.g. XENON1T) is encouraged. We offer a new explanation of why grand unification theories involving only luminous matter may be fatally flawed.
