Topological portals from matter to antimatter

TL;DR

This paper explores how topological quantum gravity effects, involving micro-black holes with baryon hairs, could induce neutron-antineutron transitions and neutron-mirror neutron mixings without destabilizing protons, suggesting testable experimental signatures.

Contribution

It proposes a novel mechanism for neutron-antineutron oscillations via topological quantum gravity effects involving micro-black holes with baryon hairs.

Findings

Micro-black hole pairs induce neutron-antineutron transitions.

Effects do not destabilize the proton.

Potential for experimental detection of neutron-mirror neutron mixing.

Abstract

We discuss possibilities of generating a Majorana mass for the neutron from topological quantum gravity effects which survive at mesoscopic scales from decoherence. We show how virtual micro-black hole (BH) pairs with skyrme/baryon hairs induce a neutron-antineutron transition which can be tested in next generation of experiments. Such effects do not destabilize the proton. We also discuss how BHs with mix ordinary and mirror baryon hairs can mediate neutron-mirror neutron mixings.
