High energy particle collisions in static, spherically symmetric black-hole-like wormholes

TL;DR

This paper explores high-energy particle collisions in wormholes resembling black holes, revealing conditions under which collision energies become extremely large, thus providing insights into distinguishing black holes from wormholes.

Contribution

It generalizes the analysis of particle collision energies from Damour-Solodukhin wormholes to a broader class of static, spherically symmetric black-hole-like wormholes.

Findings

High center-of-mass energies occur in wormhole collisions when metric differences are small.

The study extends previous models to more general static, spherically symmetric wormholes.

Results suggest potential observational signatures to differentiate wormholes from black holes.

Abstract

A Damour-Solodukhin wormhole with a metric which is similar to a Schwarzschild black hole seems to be a black hole mimicker since it is difficult to distinguish them by practical astrophysical observations. In this paper, we investigate a center-of-mass energy for the collision of two test particles in the Damour-Solodukhin wormhole spacetime. We show that the center-of-mass energy for the head-on collision of the particles is large if the difference between the metrics of the wormhole and the black hole is small. To deeply understand the high energy particle collision, we generalize the head-on collision to static, spherically symmetric black-hole-like wormholes.
