TL;DR
This paper reports on the SLIM experiment's search for intermediate mass magnetic monopoles at high altitude, setting a flux upper limit based on over four years of data collection.
Contribution
It presents the first large-scale high-altitude search for intermediate mass magnetic monopoles and establishes new flux upper limits for downgoing fast monopoles.
Findings
Flux upper limit of 1.3 x 10^{-15} cm^{-2} s^{-1} sr^{-1} at 90% C.L.
No monopoles detected in the four-year exposure.
Sensitive to monopoles with masses between 10^5 and 10^{12} GeV.
Abstract
The SLIM experiment was a large array of nuclear track detectors located at the Chacaltaya high altitude Laboratory (5230 m a.s.l.). The detector was in particular sensitive to Intermediate Mass Magnetic Monopoles, with masses 10^5 < M <10^{12} GeV. From the analysis of the full detector exposed for more than 4 years a flux upper limit of 1.3 x 10^{-15} cm^{-2} s^{-1} sr^{-1} for downgoing fast Intermediate Mass Monopoles was established at the 90% C.L.
