The Search for Magnetic Monopoles

TL;DR

This paper reviews the historical context, properties, and ongoing experimental efforts, including LHC's MoEDAL, to detect magnetic monopoles produced in accelerators and cosmic sources, and discusses future high-altitude searches.

Contribution

It provides a comprehensive overview of magnetic monopole searches, highlighting recent experimental advances and proposing future high-altitude experiments to explore fluxes below the Parker Bound.

Findings

LHC's MoEDAL experiment is specifically designed to detect magnetic monopoles.

Current searches have not yet observed monopoles, setting upper flux limits.

Proposals for high-altitude laboratories aim to extend the search to GUT scale fluxes.

Abstract

After a short historical introduction and description of the properties of the magnetic monopole we briefly discuss the search for monopoles produced at accelerators and from the cosmos. We present in a little more detail the latest LHC experiment, MoEDAL, specifically designed to continue the search for the magnetic monopole and other highly ionizing messengers of new physics at the TeV scale. Lastly we mention a proposal to continue the search for monopoles with flux below the Parker Bound up to the GUT scale at a high altitude laboratory.
