Black Hole Relics in String Gravity: Last Stages of Hawking Evaporation

TL;DR

This paper investigates black hole evaporation in string gravity, demonstrating that black holes leave stable relics instead of disappearing, which could contribute to dark matter and be detectable experimentally.

Contribution

It introduces a model showing black hole remnants in string gravity, challenging the traditional view of complete evaporation in general relativity.

Findings

Black holes do not fully evaporate in the string gravity model.

Remnants could constitute a significant part of dark matter.

Potential for experimental detection of black hole relics.

Abstract

One of the most intriguing problem of modern physics is the question of the endpoint of black hole evaporation. Based on Einstein-dilaton-Gauss-Bonnet four dimensional string gravity model we show that black holes do not disappear and that the end of the evaporation process leaves some relic. The possibility of experimental detection of the remnant black holes is investigated. If they really exist, such objects could be a considerable part of the non baryonic dark matter in our Universe.
