A new bound on supersymmetric Q-balls

Abstract

Stable baryonic Q-balls, which appear in supersymmetric extensions of the Standard Model, could form at the end of cosmological inflation from fragmentation of the Affleck-Dine condensate. They can be dark matter. The existing bounds rely on the ability of Super-Kamiokande detector to trigger on a slowly moving bright source, which may be difficult for techinical reasons. We present a weaker but more robust bound based on the flux of neutrinos produced by relic Q-balls interacting in Earth.
