Charged Black Holes and Constraints on Baryon Asymmetry

TL;DR

This paper explores how the properties of charged black holes, constrained by the no-hair theorem, can be used to understand early universe conditions and the epoch of baryon asymmetry formation.

Contribution

It investigates the implications of black hole charge and angular momentum constraints for primordial black hole formation and early universe conditions.

Findings

Constraints on black hole charge and angular momentum from no-hair theorem.

Potential to use black holes as probes of early universe baryon asymmetry.

Insights into the epoch of baryon asymmetry based on black hole formation scenarios.

Abstract

The no-hair theorem, which postulates that all black holes can be completely characterized by only three externally observable parameters: mass, electric charge, and angular momentum, sets constraints on both the maximal angular momentum and maximal electric charge. In this work, we would explore the consequence of these for the formation of primordial black holes in the early universe and also the formation of black holes due to collapse of dark matter configurations and how this could be used to probe the conditions in the very early universe and constrain the epoch when baryon asymmetry was established.
