Title: Primordial Black Holes from Supersymmetry in the Early Universe

Abstract

Supersymmetric extensions of the standard model generically suggest that in the early universe a scalar condensate can form and fragment into Q-balls before decaying. If the Q-balls dominate the energy density for some period of time, the relatively large fluctuations in their number density can lead to formation of primordial black holes (PBH). Other scalar fields, unrelated to supersymmetry, can play a similar role. For a general charged scalar field, this robust mechanism can generate black holes over the entire mass range allowed by observational constraints, with a sufficient abundance to account for all dark matter in some parameter ranges. In the case of supersymmetry the mass range is limited from above by 1023g. We further comment on the role that topological defects can play for PBH formation in a similar fashion.
