TL;DR

This paper introduces two novel high-energy particle collision scenarios near wormholes, enabling unbounded energies without requiring particles from different mouths or infinity, with potential implications for astrophysics.

Contribution

It presents new collision scenarios near wormholes that allow for infinite energy outcomes without particles originating from different mouths or infinity.

Findings

Indefinitely large energy in static wormholes

Super-Penrose process in rotating wormholes

Particles oscillating near the throat can collide with high energies

Abstract

We suggest two new scenarios of high-energy particle collisions in the background of a wormhole. In scenario 1 the novelty consists in that the effect does not require two particles coming from different mouths. Instead, all such scenarios of high energy collisions develop, when an experimenter sends particles towards a wormhole from the same side of the throat. For static wormholes, this approach leads to indefinitely large energy in the center of mass. For rotating wormholes, it makes possible the super-Penrose process (unbounded energies measured at infinity). In scenario 2, one of colliding particles oscillates near the wormhole throat from the very beginning. In this sense, scenario 2 is intermediate between the standard one and scenario 1 since the particle under discussion does not come from infinity at all.
