- Higgs inflation and primordial black hole

I've found highly cited papers that explains inflation with the Higgs as the inflaton and primordial black hole as the dark matter, for examples,

These papers solve the inflation with the Higgs and Dark matter with PBH without introducing new particles.

### Primordial Black Hole production in Critical Higgs Inflation

Primordial Black Holes (PBH) arise naturally from high peaks in the curvature power spectrum of near-inflection-point single-field inflation, and could constitute today the dominant component of the dark matter in the universe. In this letter we explore the possibility that a broad spectrum of PBH is formed in models of Critical Higgs Inflation (CHI), where the near-inflection point is related to the critical value of the RGE running of both the Higgs self-coupling λ(μ) and its non-minimal coupling to gravity ξ(μ). We show that, for a wide range of model parameters, a half-domed-shaped peak in the matter spectrum arises at sufficiently small scales that it passes all the constraints from large scale structure observations. The predicted cosmic microwave background spectrum at large scales is in agreement with Planck 2015 data, and has a relatively large tensor-to-scalar ratio that may soon be detected by B-mode polarization experiments. Moreover, the wide peak in the power spectrum gives an approximately lognormal PBH distribution in the range of masses 0.01−100M⊙, which could explain the LIGO merger events, while passing all present PBH observational constraints. The stochastic background of gravitational waves coming from the unresolved black-hole-binary mergers could also be detected by LISA or PTA. Furthermore, the parameters of the CHI model are consistent, within 2σ, with the measured Higgs parameters at the LHC and their running. Future measurements of the PBH mass spectrum could allow us to obtain complementary information about the Higgs couplings at energies well above the EW scale, and thus constrain new physics beyond the Standard Model.

arXiv:1912.12032Primordial black holes are produced in a minimal UV extension to the Higgs inflation with an included R2 term. We show that for parameters consistent with Standard Model measurements and Planck observation results lead to MPBH∈(10−16,10−15)M⊙ primordial black holes with significant abundance, which may consist the majority of dark matter.
