Looking for magnetic monopoles at LHC with diphoton events

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 γ γ 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. Pacs: 14.80.Hv, 95.30.Cq,

Production of magnetic monopoles and monopolium in peripheral collisions

“…As the massive central system requires a great amount of energy, there are very few energetic photons produced by a ionic projectile, diminish the cross section. with the previous results [16][17][18], the present one for both cases are agree with the previous results found in the literature.…”

Searches for magnetic monopoles and beyond with MoEDAL at the LHC

“…Monopolium is a neutral state, hence it is difficult to detect directly at a collider detector, although its decay into two photons would give a rather clear signal for the ATLAS and CMS detectors [25,26], which however would not be visible in the MoEDAL detector. Nevertheless according to a novel proposal [27], the LHC radiation detector systems can be used to turn the LHC itself into a new physics search machine by detecting final-state protons pp → pX p (X are centrally produced particles), exiting the LHC beam vacuum chamber at locations determined by their fractional momentum losses.…”

At high central masses M X > 150 GeV, the photon-photon process dominates making this technique appealing for detecting monopolia, which are expected to be produced in γγ fusion [24,25].…”

Status of Searches for Magnetic Monopoles

“…The observability of monopoles and monopolium, the monopole-antimonopole bound state [103], in the γγ channel for monopole masses in the range 500-1000 GeV is considered in [104].…”
