Semiclassical geons at particle accelerators

TL;DR

This paper proposes that certain stable, self-gravitating objects with discrete mass and charge spectra could be produced in current particle accelerators, supported by a solvable model within modified gravity theories.

Contribution

It introduces a model within Palatini formalism of gravity showing the potential existence of detectable semiclassical geons at particle accelerators.

Findings

Stable self-gravitating objects with discrete spectra are theoretically possible.

Nonlinear electromagnetic effects can significantly reduce their mass spectrum.

Such objects might be produced or observed in existing particle accelerator experiments.

Abstract

We point out that in certain four-dimensional extensions of general relativity constructed within the Palatini formalism stable self-gravitating objects with a discrete mass and charge spectrum may exist. The incorporation of nonlinearities in the electromagnetic field may effectively reduce their mass spectrum by many orders of magnitude. As a consequence, these objects could be within (or near) the reach of current particle accelerators. We provide an exactly solvable model to support this idea.
