Primordial black holes and secondary gravitational waves from the Higgs field

TL;DR

This paper introduces a novel Higgs-based inflationary model that explains dark matter as primordial black holes and predicts observable secondary gravitational waves, linking particle physics with cosmological phenomena.

Contribution

It demonstrates for the first time that the Higgs field can drive inflation, produce primordial black holes, and generate detectable gravitational waves, unifying multiple cosmological observations.

Findings

Higgs-driven inflation consistent with CMB data

Enhanced small-scale curvature perturbations lead to primordial black holes

Secondary gravitational waves are predicted to be observable by future detectors

Abstract

We devise a novel mechanism and for the first time demonstrate that the Higgs model in particle physics can drive the inflation to satisfy the cosmic microwave background observations and simultaneously enhance the curvature perturbations at small scales to explain the abundance of dark matter in our universe in the form of primordial black holes. The production of primordial black holes is accompanied by the secondary gravitational waves induced by the first order Higgs fluctuations which is expected observable by space-based gravitational wave detectors. We propose possible cosmological probes of Higgs field in the future observations for primordial black holes dark matter or stochastic gravitational waves.
