Black Holes as a Collider of High Energy Particles

TL;DR

This paper explores how black holes, including Kerr and Schwarzschild types, can act as natural high-energy particle colliders through the BSW process, potentially producing particles with extremely high energies.

Contribution

It demonstrates that both Kerr and Schwarzschild black holes can serve as sources of high-energy particles in the polar region, expanding the understanding of black holes as natural particle accelerators.

Findings

Black holes can act as natural high-energy particle colliders.

Both Kerr and Schwarzschild black holes can produce high-energy particles.

High-energy particle production occurs in the polar region of black holes.

Abstract

According to the Banados-Silk-West (BSW) process, rotating black holes can act as particle colliders capable of achieving arbitrarily high center-of-mass energy (CME), provided that a specific angular momentum of one of the particles is present. In this discussion, we demonstrate that both Kerr black holes and Schwarzschild black holes could serve as potential sources of high-energy particles in the polar region.
