Q-balls in the MSSM

Abstract

Q-balls are generically present in models with softly broken low-energy supersymmetry. We discuss the properties of these non-topological solitons, which can precipitate a new kind of first-order phase transition in the early Universe and have other important implications for cosmology and experiment.
