Looking for magnetic monopoles at LHC with diphoton events

TL;DR

This paper explores the potential to detect magnetic monopoles and monopolium at the LHC through diphoton events, focusing on masses below 1 TeV, and suggests the LHC is well-suited for such discoveries.

Contribution

It proposes new detection methods for magnetic monopoles and monopolium at the LHC in the diphoton channel for masses 500-1000 GeV.

Findings

LHC can potentially discover monopoles below 1 TeV with current energies.

Diphoton channel is promising for detecting monopoles and monopolium.

Detection prospects are favorable with 5 fb$^{-1}$ of data.

Abstract

Magnetic monopoles have been a subject of interest since Dirac established the relation between the existence of monopoles and charge quantization. The intense experimental search carried thus far has not met with success. The Large Hadron Collider is reaching energies never achieved before allowing the search for exotic particles in the TeV mass range. In a continuing effort to discover these rare particles we propose here other ways to detect them. We study the observability of monopoles and monopolium, a monopole-antimonopole bound state, at the Large Hadron Collider in the $\gamma \gamma$ channel for monopole masses in the range 500-1000 GeV. We conclude that LHC is an ideal machine to discover monopoles with masses below 1 TeV at present running energies and with 5 fb$^{-1}$ of integrated luminosity.
