Saturons and their role in particle physics and cosmology
"Saturons" are macroscopic objects that saturate the field theoretic upper bound on microstate degeneracy. Due to this feature, saturons and black holes belong to the same universality class with common key properties. However, as opposed to black holes, saturons can emerge in renormalizable gauge theories, in the form of solitons, baryons and other bound states. After reviewing the general properties of saturons, we discuss their potential implications for particle physics and cosmology. In particular, saturons are interesting candidates for dark matter. Due to the maximal microstate entropy, the saturon dark matter can form as a result of a direct quantum transition from the radiation thermal bath. Correspondingly, they can form a superheavy dark matter at very low temperatures. Saturons can provide a new type of source for primordial black holes. They also serve as a theoretical laboratory for understanding and predicting new features of black holes that can be imprinted in gravitational radiation from black hole mergers.
