Limits on Production of Magnetic Monopoles Utilizing Samples from the DO and CDF Detectors at the Tevatron

TL;DR

This paper establishes experimental upper limits on the production of magnetic monopoles at the Tevatron collider, using samples from the D0 and CDF detectors, and extends previous bounds for various magnetic charges.

Contribution

It provides the first limits on monopole production at the Tevatron using trapped monopoles in detector materials, improving upon previous bounds for multiple magnetic charge values.

Findings

No monopoles detected within the sensitivity of the experiment.

Set 90% confidence level limits on monopole production cross-sections and masses.

Extended bounds for monopoles with charges of 1, 2, 3, and 6 times the Dirac charge.

Abstract

We present 90% confidence level limits on magnetic monopole production at the Fermilab Tevatron from three sets of samples obtained from the D0 and CDF detectors each exposed to a proton-antiproton luminosity of $\sim175 {pb}^{-1}$ (experiment E-882). Limits are obtained for the production cross-sections and masses for low-mass accelerator-produced pointlike Dirac monopoles trapped and bound in material surrounding the D0 and CDF collision regions. In the absence of a complete quantum field theory of magnetic charge, we estimate these limits on the basis of a Drell-Yan model. These results (for magnetic charge values of 1, 2, 3, and 6 times the minimum Dirac charge) extend and improve previously published bounds.
