Primordial Black Holes in Induced Gravity Inflationary Models with Two Scalar Fields

TL;DR

This paper introduces a two-field inflationary model with induced gravity that aligns with observational data and supports primordial black hole formation, potentially explaining dark matter.

Contribution

The paper develops a novel two-scalar-field inflationary model with induced gravity, linking it to primordial black hole formation and dark matter candidates.

Findings

Model consistent with recent observational data

Supports formation of primordial black holes

Primordial black holes as dark matter candidates

Abstract

We propose a two-field inflationary model with the induced gravity term. Using conformal transformation of the metric, we get the chiral cosmological model with two scalar fields. We demonstrate that the constructed inflationary model does not contradict to the recent observation data and is suitable for primordial black hole (PBH) formation. The estimation of PBH masses allows to consider PBHs as dark matter candidates.
