Do microscopic stable black holes contribute to dark matter?

TL;DR

This paper explores the potential role of hypothetical stable microscopic black holes as dark matter candidates, analyzing their theoretical properties, experimental signatures, and astrophysical implications.

Contribution

It introduces Lovelock black holes in odd dimensions as a model and examines their possible contribution to dark matter and observable effects.

Findings

Black holes could contribute to dark matter if stable.

Passage and collisions of black holes have detectable signatures.

Black holes may influence stellar evolution.

Abstract

We investigate some of the experimental, observational and theoretical consequences of hypothetical stable black holes in the mass range between the electro-weak scale and the Planck mass, 2.4$\times 10^{15}$ TeV. For the purpose of calculations we use Lovelock black holes in odd dimensions. If such black holes exist they contribute to dark matter. We show that the passage of the black holes through matter and the collision of black holes have a well defined experimental signature. Depending on their cross section and energy they also accumulate in stars and influence their development.
