Primordial Black Hole Production in Inflationary Models of Supergravity with a Single Chiral Superfield

TL;DR

This paper introduces a supergravity inflationary model with a single chiral superfield that can produce primordial black holes as dark matter candidates and allows for adjustable supersymmetry breaking.

Contribution

It presents a novel double inflection point inflationary model in supergravity with a single chiral superfield, enabling PBH production and tunable SUSY breaking.

Findings

Model successfully generates primordial black holes at small scales.

Allows for small, adjustable SUSY breaking with a tiny cosmological constant.

Potential to explain a significant fraction of dark matter.

Abstract

We propose a double inflection point inflationary model in supergravity with a single chiral superfield. Such a model allows for the generation of primordial black holes(PBHs) at small scales, which can account for a significant fraction of dark matter. Moreover in vacuum it is possible to give a small and adjustable SUSY breaking with a tiny cosmological constant.
