Abstract

Supersymmetry predicts multiple flat directions, some of which carry a net baryon or lepton number. Condensates in such directions form during inflation and later fragment into Q balls, which can become the building blocks of primordial black holes. Thus, supersymmetry can create conditions for an intermediate matter-dominated era with black holes dominating the energy density of the Universe. Unlike particle matter, black holes decay suddenly enough to result in an observable gravitational wave signal via the poltergeist mechanism. We investigate the gravitational wave signatures of supersymmetry realized at energy scales that might not be accessible to present-day colliders.
