| contents | During a cosmological first-order phase transition in a dark sector, fermion dark matter particles $χ$ can form macroscopic Fermi balls that collapse to primordial black holes (PBHs) under certain conditions. The evaporation of the PBHs produces a boosted $χ$ flux, which may be detectable if $χ$ couples to visible matter. We consider the interaction of $χ$ with electrons, and calculate signals of the dark matter flux in the XENON1T, XENONnT, Super-Kamiokande and Hyper-Kamiokande experiments. A correlated gravitational wave signal from the phase transition can be observed at THEIA and $μ$Ares. An amount of dark radiation measurable by CMB-S4 is an epiphenomenon of the phase transition. |
