Effects of acceleration on the collision of particles in the rotating black hole spacetime

TL;DR

This paper investigates how black hole acceleration influences particle collision energies and high-velocity collision regions, revealing complex dependencies and richer physics in accelerating black hole spacetimes.

Contribution

It provides the first detailed analysis of how black hole acceleration affects particle collision energies and collision belt configurations.

Findings

Acceleration alters the center-of-mass energy dependence near the horizon.

Acceleration modifies the shape and location of high-velocity collision belts.

Different behaviors are observed depending on proximity to the event horizon or acceleration horizon.

Abstract

We study the collision of two geodesic particles in the accelerating and rotating black hole spacetime and probe the effects of the acceleration of black hole on the center-of-mass energy of the colliding particles and on the high-velocity collision belts. We find that the dependence of the center-of-mass energy on the acceleration in the near event-horizon collision is different from that in the near acceleration-horizon case. Moreover, the presence of the acceleration changes the shape and position of the high-velocity collision belts. Our results show that the acceleration of black holes brings richer physics for the collision of particles.
