BSW process of the slowly evaporating charged black hole

TL;DR

This paper investigates the BSW process near slowly evaporating charged black holes, showing it can occur without the black hole being extremal, unlike previous assumptions, especially when the black hole is not nearly huge.

Contribution

It demonstrates that the BSW process can occur near non-extremal, slowly evaporating charged black holes, expanding understanding beyond extremal black hole scenarios.

Findings

BSW process occurs near slowly evaporating charged black holes

Black holes do not need to be extremal for BSW to occur

Process is relevant when black holes are not nearly huge

Abstract

In this paper, we study the BSW process of the slowly evaporating charged black hole. It can be found that the BSW process will also arise near black hole horizon when the evaporation of charged black hole is very slow. But now the background black hole does not have to be an extremal black hole, and it will be approximately an extremal black hole unless it is nearly a huge stationary black hole.
