Description
In non-minimal dark-matter models such as Dynamical Dark Matter (DDM), the mass spectrum of the dark-sector states plays a crucial role in dark-matter phenomenology. In this talk, I examine one natural method in which a particularly auspicious mass spectrum can be generated for an ensemble of such states via early-universe processes which are essentially random. Despite this inherent randomness, a characteristic mass spectrum statistically emerges in which the density of states for the ensemble decreases in a predictable way as a function of mass. I discuss the phenomenological implications of such "emergent" mass spectra within the DDM framework and explore some of the possibilities for model-building to which they give rise.
