A cosmological signature of the Higgs instability: Primordial black holes
Abstract
A remarkable property of the Standard Model Higgs potential is that it develops an instability at a scale of the order of 10^{11} GeV. The cosmological implications of this feature give us the possibility to get an insight of physics at scales which are inaccessible at colliders. We show in the paper by ESPINOSA J. R. et al., Phys. Rev. Lett., 120 (2018) 121301, that a possible cosmological signature of the instability could be the generation of dark matter in the form of primordial black holes, seeded by the fluctuations of the Higgs field generated during inflation.
