Properties and signatures of supersymmetric Q-balls

Abstract

Supersymmetric extensions of the Standard Model predict the existence of Q-balls with baryon and lepton numbers. Stable Q-balls can form at the end of inflation from the fragmentation of the Affleck-Dine condensate and can exist as dark matter. The best current limits come from Super-Kamiokande and MACRO. The search beyond these limits can be conducted using the future water Cherenkov detectors.
