Testing super heavy dark matter from primordial black holes with gravitational waves
Original language description
Ultra-light primordial black holes with masses M BHBH < 1099 g evaporate before big-bang nucleosynthesis producing all matter fields, including dark matter, in particular super-heavy dark matter: M DMDM ≳ 101010 GeV. If the dark matter gets its mass via U(1) symmetry-breaking, the phase transition that gives a mass to the dark matter also produces cosmic strings which radiate gravitational waves. Because the symmetry-breaking scale ΛCSCS is of the same order as M DMDM, the gravitational waves radiated by the cosmic strings have a large enough amplitude to be detectable across all frequencies accessible with current and planned experimental facilities.
