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.

Higgs vacuum stability has important consequences for cosmology. In particular, we argue that if the Higgs vacuum is metastable, then the dark matter cannot contain a single black hole of mass less

We devise a novel mechanism and for the first time illustrate that the Higgs model in particle physics can drive the inflation to satisfy cosmic microwave background observations and simultaneously
On the Cosmological Stability of the Higgs Instability
The Standard Model Higgs potential becomes unstable at large Higgs field values where its quartic coupling becomes negative. While the tunneling lifetime of our current electroweak vacuum is
Primordial black holes from Higgs vacuum instability: avoiding fine-tuning through an ultraviolet safe mechanism
TLDR
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.
Implications of the detection of primordial gravitational waves for the Standard Model
The detection of primordial gravitational waves would not only have extraordinary implications for our understanding of early cosmology, but would also give non-trivial constraints on Standard Model
Cosmological Aspects of Higgs Vacuum Metastability
The current central experimental values of the parameters of the Standard Model give rise to a striking conclusion: metastability of the electroweak vacuum is favoured over absolute stability. A
Primordial black holes as dark matter through Higgs field criticality
We study the dynamics of a spectator Higgs field which stochastically evolves during inflation onto near-critical trajectories on the edge of a runaway instability. We show that its fluctuations do
A cosmological signature of the SM Higgs instability: gravitational waves
A fundamental property of the Standard Model is that the Higgs potential becomes unstable at large values of the Higgs field. For the current central values of the Higgs and top masses, the

We review and discuss recent work exploring the implications of the Higgs field for early universe cosmology, and vice versa. Depending on the model under consideration, the Higgs may be one of a few
Connecting the Higgs potential and primordial black holes
It was recently demonstrated that small black holes can act as seeds for nucleating decay of the metastable Higgs vacuum, dramatically increasing the tunneling probability. Any primordial black hole

TLDR
An upper bound on the pole mass of the top quark is derived by requiring that the standard model be stable all the way up to the Planck mass scale and conservatively estimate the theoretical uncertainty.
