# Cosmological Signature of the Standard Model Higgs Vacuum Instability: Primordial Black Holes as Dark Matter.

@article{Espinosa2018CosmologicalSO, title={Cosmological Signature of the Standard Model Higgs Vacuum Instability: Primordial Black Holes as Dark Matter.}, author={J. R. Espinosa and D Racco and Antonio Walter Riotto}, journal={Physical review letters}, year={2018}, volume={120 12}, pages={ 121301 } }

For the current central values of the Higgs boson and top quark masses, the standard model Higgs potential develops an instability at a scale of the order of 10^{11} GeV. We show that a cosmological signature of such instability could be dark matter in the form of primordial black holes seeded by Higgs fluctuations during inflation. The existence of dark matter might not require physics beyond the standard model.

It is shown how fine-tuning can be naturally avoided by coupling the Higgs to a very heavy scalar with mass that stabilises the potential in the deep ultraviolet, but preserving the basic feature of the mechanism which is built within the Standard Model.
