Topological Portals from Matter to Antimatter

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.

Automated summary

In this paper, we discuss the possibilities of generating a Majorana mass for the neutron through topological quantum gravity effects at mesoscopic scales. Furthermore, we explore the effects of virtual micro-black holes on neutron-antineutron transitions and neutron-mirror neutron mixings.
